A Fully automated extracting tool. This is not a WinRAR or WinZIP replacement but quite a useful util when you want to extract large quantum of archives. The program makes a queue of every rar added to the list and extract them one by one. This way you can peacefully play your games (or sleep) while extracting. It also have optional functions to cleanup (removing archives after extract). You should try it, it is free and you'll get a notice when a program update is available, that way you'll always have the latest version.

A simple GUI program. (Compiled EXE file.) Runs on all Windows versions. No installation necessary. The easiest option.
The most complete MSI unpacker program available. (A program written as a webpage and powered by VBScript.) The most flexible option.
Runs on all Windows versions. For 'power users' who may want to inspect an MSI by feature, component, etc. Also includes tools for repackaging MSI or MSM contents as a normal installer. - A simple VBScript. (A plain text file.) No interface.
Just drop an MSI onto the script and it gets unpacked. The script functionality can be customized by anyone who knows VBScript. (Runs on all Windows versions but may not work as drag/drop on many Vista/7 PCs due to problems with permission settings.) General MSI info. MSI is a way to install Windows software. MSI is a free database program.
MSI is a handy tool for scripters. A few years ago Microsoft developed a new system for installing software onto Windows. The system is referred to as 'Windows Installer'. Software installed by Windows Installer comes packaged in a file with the extension '.msi'.(Sometimes the MSI file is packaged inside an EXE file.) For the purposes of this webpage, Windows Installer and MSI are defined separately, with MSI being the database and object model, while 'Windows Installer' refers only to Microsoft's use of MSI files for software installation. An MSI file is actually an SQL database, for all practical purposes. Technically it's a Compound Storage File, like a Word.doc file.
But the functions available for working with MSIs present it as a simple SQL database. A scriptable object provided by msiexec.exe (the WindowsInstaller.Installer object) is basically a simple SQL 'engine', offering an extensive set of functions for accessing and manipulating an MSI database. (The relatively limited query options, a subset of SQL, have sometimes been referred to as 'WQL' or Windows Query Language.) Windows Installer (WI) refers to using MSI database files as the 'housing' for a software installation. An MSI file used to install software through WI contains the software install settings and usually contains the software itself, packed inside the MSI.
Unfortunately, the Windows Installer system is extremely - even bizarrely - complex. It uses an MSI database that contains approximately 80 tables, with extensive cross-referencing between the various columns of those tables. The structure of MSI databases, when they are used as Windows Installer installation files, is so complex, convoluted and poorly designed, with data so heavily cross-referenced - and the available tools are so limited - that few software developers using WI actually create their own installation files. It's a rather absurd situation: Microsoft created a comprehensive software installation system for Windows, which should have simplified the process. The Windows Installer system is supposed to be doing all of the 'heavy lifting'.
So there's no reason that people should need anything more than an INI file to create a full-featured installer. Yet instead of making software installation easier, Windows Installer has made it far more complex. Software developers end up needing other, specialized software developers. To write special software.
That makes sense of Microsoft's installer software. In order to produce specialized software. To install their software. The situation has become so ridiculous that Acresso Software, the makers of InstallShield, are able to charge $2,000+- for their InstallShield 2010, and the installer for InstallShield itself is about 170 MB! Presumably that ends up being about 1/2 GB of absurdly overpriced software, once the 170 MB package has been installed on-disk. Just to build MSI packages for installing software.
Perhaps Microsoft deliberately made a mess of Windows Installer so that InstallShield, Wise and other 3rd-party companies could stay in business. After all, if Microsoft had created a simple, intuitive and functional system for installing software onto Windows then no one would have any reason to pay for 3rd-party installer software, and that might leave Microsoft open to more lawsuits. Whatever the real story is behind the design of the Windows Installer system, as you may have guessed by this point, the downloads and information here are not intended to help anyone use the Windows Installer system to build a software installer. Why be concerned with MSI files?
While Windows Installer is arguably of little value for its intended purpose of installing software, it is scriptable. That is, the Windows Installer 'object model' provides a way for script or other programming tools to access an MSI file. There are three ways to take advantage of that design: 1) Inspecting, unpacking and/or editing software installers. Some companies package their software installations as MSI files because it's Microsoft's 'official' method.
(Any company that wants to add an official Microsoft 'Approved for Windows' logo to their software packaging must use MSI installation.) That can be an advantage for the software customer because an MSI file is entirely transparent, given the right tools. VBScript can be used to unpack, document, and even alter the installation parameters of an MSI installer. You can unpack an MSI file, extract the files inside, and find out what Registry entries will be made when you install the software. (See the MSI Unpacker below.) You can also edit the MSI database directly to remove problematic limitations that may prevent software installing for one reason or another. (See the MSI Editor below.) 2) Bypassing MSI limitations (for software developers). The original inspiration for the MSI utilities here was a problem that arose several years ago. A small, custom Text-To-Speech utility written for a blind person required SAPI 5 Text-To-Speech support.
It turned out that Microsoft had only provided two ways to install SAPI 5 TTS support. One option was to just install the 98 MB SAPI SDK on the target machine. The other option was to study the Windows Installer system, then remake the utility installer as an MSI, then download 100+ MB of files in the form of 'merge modules' (.msm files), and finally, figure out how to pack the necessary parts of the necessary merge modules into the MSI. Those options were both ridiculous, just to install a handful of support libraries that totalled about 6 MB. The sample VBScript installer for SAPI 5 TTS support (included with the MSI Unpacker utility download) was the upshot of that dilemma.
It uses the Windows Installer object model, through VBScript, to generate a VBScript installer for only the features and/or components of a software installer or merge module desired, without needing to install via MSI. The sample demonstrates how the MSI object model can be used to bypass MSI limitations - and MSI usage altogether - when installing software that may require Microsoft redistributables. 3) Using MSI files as databases. The MSI system used by Windows Installer is essentially a free SQL database program that is installed on nearly all Windows PCs. The scripting functionality provided through the WindowsInstaller.Installer object enables a fairly simple VBScript to carry out all the basic functions needed to use an MSI file as an SQL database. Is an example of how MSI databases can be used. The ZipFinder started as a blank MSI file.
VBScript was used in combination with the WindowsInstaller.Installer object to create tables in the blank MSI and load them with the relevant zip code and area code data. The ZipFinder interface is a simple webpage that uses the same WindowsInstaller.Installer object, via webpage scripting, to read from and write to the zip code database - a list of some 55,000 US zip codes. Is another example of just how useful an MSI file can be when used as a simple database. Windows Installer Documentation: The VBScript class provided here, along with the associated documentation (included with the MSI editor) provide the basics needed to use MSI files as custom databases. If you want more information about Windows Installer and the WindowsInstaller.Installer object, there is a good help file named msi.chm. The help file is part of the MSI v.
1.1 SDK (8MB) that should be at this link:. As of this writing, Windows Installer is up to version 4.5, but v.
4 is Vista-only (even though, strangely, a late version of v. 4.5 is redistributable to XP SP2) and the changes between versions seem to be minimal, so the v. 1.1 help should be adequate. 1.1 has the added advantage that support for it is already installed on nearly all PCs. Windows Installer is designed such that each new version breaks compatibility with the last. In other words, if you create an MSI file with v.
4.5 of Windows Installer you won't be able to use it on most Windows PCs, even if it's just an empty MSI. The target machine will have to have v. 4.5 of the Windows Installer system installed. But if you still want the more recent v. 4.5 help try this link:.
Who can use the downloads on this page? Most of the code here is composed of VBScripts and scripted DHTML webpage utilities. With the exception of the jsMSIx.exe unpacker and the jsMSI.dll COM (ActiveX) library, it is all simple text: VBScript, HTML and CSS. The downloads here are especially designed for use by VBScripters and/or people working with Windows Installer. But you don't have to know VBScript, HTML, or CSS. The MSI unpacker and editor, and the zip code utility, are interactive webpage programs that might be useful to almost anyone. If you are familiar with VBScript, you can use the free utilities here for your own purposes in working with MSI files, or use them as code samples for guidance in using the MSI object model.
Since these programs are composed of plain text script code, they can also be altered and new functionality can be added as necessary. JsMSIx.exe - Simple MSI/MSM Unpacker Program jsMSIx.exe is a small program with no installation required and no extra files needed other than normal system files that are pre-installed on nearly all Windows PCs. No muss, no fuss.
Just run jsMSIx.exe, browse for an MSI file, and unpack it. JsMSIx.exe can also provide MSI information, listing files and Registry settings in the MSI without unpacking it. This is the most convenient unpacker for non-technical people. It can be used as a normal Windows program or as a command-line utility. For Linux: jsMSIx.exe is probably the best option for people using Linux because it does not require support for VBScript, Internet Explorer, or COM libraries.
Everything is built into a single, small standalone program. It also has simple command line functionality to unpack an MSI and optionally select the destination folder for unpacking. The only notable dependencies are cabinet.dll, msvbvm60.dll and msi.dll. Those files are all pre-installed on virtually all Windows PCs and should all be installable (or have native versions) through WINE. (Last update: April, 2014. In the past there have been some MSIs that did not unpack properly due to errors in the Directory Table.
The latest update includes a complete rewrite of the folder/file sorting code that parses that table. See download README file for full update history.) MSI Unpacker Utility - An HTA Webpage Program The MSI Unpacker utility is a webpage program (HTA) for working with MSI and MSM Windows Installer files. It is designed for use by anyone who might want to inspect software before installing it. The MSI Unpacker can be used to open MSI and MSM files. It can extract files, document the contents, and list Registry entries created by the installer. It can also detail specific parts of an installation.
For instance, if you are installing an office suite, the MSI Unpacker can tell you which files and Registry settings are required for just the word processor program. You can use the MSI Unpacker to inspect software before installing, or use it to create your own, customized install/uninstall packages from the parts of an MSI package that you want.
Scripts included with the MSI Unpacker can be used to generate an almost-ready-to-run script containing the Registry settings required for a given MSI program installation. That means you can rebuild an installer as a non-MSI if desired. The download includes a sample project that uses these tools to create an installer for the Microsoft Text-To-Speech runtime - a runtime that is not normally available as a separate install. This utility does not require prior knowledge of script or MSI files. Just double-click the HTA file in the download and browse for an MSI file to unpack. But inexperienced people may prefer jsMSIx (above).
The MSI/MSM Unpacker Utility is designed for people with technical expertise who may want to inspect an MSI file in detail or convert MSI installers to another type of installer. The MSI Unpacker also works with the component, allowing drag-drop of files onto HTAs and their shortcuts (or any other file type). (Last update: April, 2014.
See download for details.) Simple 'One-Click' MSI Unpacker Script The Simple 'One-Click' Unpacker is essentially the same thing as the MSI Unpacker described above, but without the Internet Explorer webpage interface, and without the extra script samples. It just unpacks MSIs and writes a log file to document the details. On Windows this is a simple drag-and-drop unpacker, useful when you just simply want to unpack an MSI and don't need to inspect the Components, Features and other technical details of the MSI. To use this utility in Windows, first download msiext2.zip (below). Open the msiext2.zip download and extract the files into a single folder. (The MSIUnpack.vbs file and the jcabxmsi.exe file must be in the same folder.) Next, put your MSI file into an empty folder. (Unpacking can create numerous files and subfolders, so it's best to put the MSI into it's own folder before unpacking.) Finally, just drop the MSI file onto MSIUnpack.vbs.
You'll get the unpacked software, with all files extracted and placed in a folder hierarchy that reflects their destination folders when the software is installed. There will also be a documentation file - an unpack log - listing included files, Registry settings that are part of the install, etc. (Note that security/permissions problems on Windows Vista/7 may prevent the drag-drop functionality from working. If you want to run with limited permissions on Vista/7 you may have to use the One-Click Unpacker via command line.) (Last update: April, 2014. See download for details.) Issues With Non-MSI Files: Getting MSIs from Inside EXEs Microsoft's general position on software installers is that they should be created as MSI files and that those MSI files should not be 'wrapped' in other files. However, there are many types of installers and Microsoft themselves are famous for not following their own directives. Many of their downloads are actually self-executing CAB files.
Some of the Microsoft program installers are actually InstallShield packages. (In both cases these are.EXE files.) And in some cases an EXE might contain multiple MSIs that call each other. If you have an unknown installer type that you are trying to open, you might try looking at the. There is a section there that has links to information and software. Perhaps the best software option is, a program that's basically just a handy GUI frontend for a collection of specialized extractor executables. (For example, it includes the well-known INNOUNP.EXE for unpacking Inno Setup installers, IsXunpack.exe for InstallShield packages, etc.) Universal Extractor (UE) saves the trouble of finding, collecting and updating these various tools. But UE cannot handle MSI files in any useful way, and it will sometimes fail with other installer files due to unsupported versions.
For instance, UE can open InstallShield installers, but only if they were created with older versions of the InstallShield program. MSI files inside EXE files It is fairly common to find software that installs from an MSI file but which is packed inside an EXE file. Some recent version InstallShield packages are designed that way, for example. If you can't get at the contents of a given installer EXE file, it's always worth checking for a hidden MSI. Open the TEMP* folder while running the installer. Leave the setup window open while checking to see what the installer unpacks.
If the installer unpacks a folder to TEMP, check there for an MSI file. If you find an MSI file, copy it to somewhere else, then cancel the install. (Setup must be left running while you check the TEMP folder because it will usually delete the files in the TEMP folder when it quits.) The resulting.MSI file will be the real program installer. * Finding the TEMP folder: It's usually C: Windows Temp on Win9x.
It will probably be down inside the 'C: Documents and Settings' mess on XP. But XP+ can have numerous TEMP folders. If you're not sure, copy this text into Notepad, save it as findTemp.vbs, and double-click the.vbs file: Set FSO = CreateObject('Scripting.FileSystemObject') MsgBox FSO.GetSpecialFolder(2) MSIs Inside EXEs Get Wacky -- the 12-09 Update As explained, the unpackers were updated slightly as of 12-09. Some newer installations, especially with Windows Installer v. 4.5, seem to be using a new and rather odd install method. In general an EXE is not part of an MSI install. The MSI itself is the installer file.
But some installs use an EXE, nevertheless. As explained in the last section, an EXE will dump an MSI file into the TEMP folder and then run it from there. The actual program files, in that case, are stored in a CAB file, which is usually embedded inside the MSI. The EXE is just an unnecessary 'wrapper' around the MSI. To unpack those MSIs without installing the software, the MSI must be fished out of the TEMP folder after starting an installation.
Then the installation can be cancelled and the MSI unpacked. With some newer installation files there is a new wrinkle. A good example is SQL Server 2008 Express from Microsoft. The download is an EXE file. (Microsoft have never recommended EXE 'wrappers' around MSIs, but Microsoft have never been in the habit of following their own instructions, either.) The EXE in this case is not just an MSI wrapper. It is actually a self-executing CAB file. If the download is converted to a CAB it can be seen to contain all of the install files, named with pre-installation code names that get changed on install, plus a handful of installation files, including an MSI file.
The SQL Server install requires Windows Installer v. 4.5, yet Windows Installer is largely superfluous in the installation. When the EXE is run it dumps it's contents into the TEMP folder, but in the process it also unpacks the install files, copies them to a program folder tree created in the TEMP folder, and renames them all to their correct post-install names! Since there is no embedded CAB in the MSI to unpack, the MSI Unpackers do not find any files and the Program Description log file written by the unpackers therefore does not list any files. In other words, this is an inside-out MSI. Instead of being an MSI with an embedded CAB inside, the MSI is actually inside the CAB.
Microsoft's SQL Server install is not alone in using this odd method, so you need to be aware of it for successful unpacking. You can recognize the new 'wacky mode' installers because when you open the TEMP folder you'll find not only an MSI but also a full program installation, ready to be copied to the appropriate folders.
The program folder is there just as it would end up being in Program Files if you completed the install! So the file unpacking is already done for you.
You can copy those folders/files out of TEMP if you want to inspect them. But there is still an MSI file as well.
The MSI still contains documentation of folders, files, Registry settings, Features, Components, etc. You can run the MSI Unpacker with that MSI file to get a log file that documents all of those things. The difference from a normal MSI is that the unpacker will not actually unpack anything, because there's nothing there to unpack. It has already been done by the installer EXE. The 12-09 update to the unpackers includes a change to make sure that the program files and their paths are listed in the final 'Program Description.txt' log, regardless of whether those files were unpacked and renamed by the unpacker, or whether they were unpacked and renamed by the installer EXE. Solving Problems: MSI Requirements Preventing a Program Installation Complications can be caused by an installer that asserts requirements. For instance, a common installer requirement that can thwart an install, and or thwart the unpacking of a setup EXE file, is the demand that a particular version of Internet Explorer be installed.
This is an especially odd requirement. In most cases the software does not even use Internet Explorer! For problems with Internet Explorer requirements, try changing the version number in this Registry value: HKEY_LOCAL_MACHINE Software Microsoft Internet Explorer Version Also, see the MSI Editor topic below.
Altering/removing install requirements is one of the uses of the MSI Editor. A unique issue is the '.Net Framework', which is Microsoft's version of the Java 'Virtual Machine' -- a set of support files needed for software written as a.Net program. Most software does not use.Net, fortunately. (The more recent version of the support files package is over 200MB!). But what if you just want to see the software, and maybe you don't want to install all of the.Net support files? For problems with demands for.Net Frameworks, if you just want to open an installer EXE file and may not want to actually install the program in question, you can spoof.Net support temporarily. For that, see.
That link should open in your browser as text. Copy the text, paste it into Notepad or another plain text editor, then save that as a file named Spoof Dotnet.vbs. Note that the file extension must be.VBS, not.TXT.
When you double-click that file you will be given an option to add or remove the DotNet spoof from the Registry. Once added, software installers will think that whatever version of the.Net Framework they want is already installed. The script adds Registry settings that say you have all 5.Net Frameworks. For good measure, it also tells querying software that you have Service Pack 3 of each Framework, and version 3 of Windows Installer. ( Caution: This script is for limited usage, for people who just want to inspect a program they are unlikely to actually use, and who do not want to install the numerous.Net support files. The script will record in the Registry that all 5.Net Frameworks are installed. Likewise, removing the spoof will remove those settings, even though you may have one or more frameworks installed.) Problems Unpacking MSIs in Windows 98 MSI files are a type of Microsoft-specific file known as a Compound File, Compound Storage File, or Compound File Binary (CFB).
OpenOffice.org and Microsoft both provide documentation for this file type. A CFB file is a flexible format consisting of a number of segments. The segments can represent different things, depending on the file type.
The purpose of the CFB format is simply to arrange those parts in an orderly structure that can be parsed. MS Word.doc files, Powerpoint files and MSI files are all CFB files.
There are two major versions of CFB files currently in use: versions 3 and 4. Version 4 was introduced with Windows 2000. Most MSIs are CFB v. 3 files; unpacking should work on Win9x regardless of the Windows Installer version. However, there are some CFB v. 4 files in use.
(One example is the Libre Office installer.) A CFB v. 4 file will not be recognized on Win98. Arc System Keygen 2016 - Download And Reviews 2016 here. Since CFB files are native to Windows itself, it is unlikely that any kind of update will solve that problem.
(On the bright side, it is very unlikely that any software packed into a v. 4 MSI file will run on Windows 9x, anyway.) If you have trouble unpacking an MSI on Win98, the first thing to do is to check the CFB version: Open the MSI file in a hex editor.
You will find that the first 8 bytes are nonsense, comprising the 'magic' bytes, which identify the file type. After that come 16 null bytes. The next 6 bytes should be either 3E 00 03 00 FE FF or 3E 00 04 00 FE FF. Those are version 3 and version 4 respectively..MSU Files.MSU files apply only to Windows Vista and later. An MSU is an update file. While MSUs have been tied into the Windows Installer system, an MSU is actually not a Windows Installer file at all.
It's just a CAB file. If you rename a.msu file to.cab you can open it with any ZIP program. Inside you'll typically find more CABs. The update files will be inside one of those CABs. (The actual content of an update will usually be breathtakingly convoluted and overproduced, with liberal sprinklings of CLSIDs, bloated XML, etc. It's not the sort of thing that one is likely to want to dissect.) Non-JSWare Tools For Handling MSIs There is a lot of confusion and misinformation online in regard to options in dealing with MSI files.
Basically, an MSI is a storage file designed to work like a simple SQL database. Microsoft provides functionality (in MSI.DLL) to manage that database. (MSI.DLL, which provides the functionality used by Windows Installer, has a dual API -- Win32-style functions for programming languages and COM Dispatch functions for use with script. Many of the tools here are VBScript-based because the scripting API is essentially the same as the programming API, and very easy to use.) The JSWare MSI unpackers are the only ones available, as of this writing, that can fully unpack an MSI and also document the Registry settings changed when the MSI install is run.
Other options: • Administrative Install - An Admin install is a Windows Installer command line option using msiexec.exe. It extracts files for multiple network installations, running the steps in the AdminExecuteSequence, if present, rather than the InstallExecuteSequence. That's not quite the same thing as unpacking. Look it up in the MSI docs if you think that might be of interest. (Also note that an Administrative Install is a restricted operation.
It can only be done with Administrator status. And it is not 'supported' in all MSIs.) Some software programs available that claim to unpack or extract from MSI files are actually just graphical 'front-ends' for doing an Administrative install.
They simply execute an msiexec command line so you don't have to type. (An example of that is a program named only 'MSI Unpacker'.) • Less MSIErables - This is a free, 'open source' program that allows one to see files in an MSI and also unpack the program. Pros: Less MSIErables has an attractive, polished interface, it's easy to use, and it works. It also provides the option to extract only one specific file from an MSI installer. Cons: Less MSIErables does not provide information about Registry settings.
And it has gigantic dependencies. (Other files required for it to work.) Less MSIErables is actually a simple wrapper GUI that requires the.Net Framework and a set of Microsoft libraries known as 'Wix'. So Less MSIErables is a multi-level wrapper around wrappers. (.Net wraps the Win32 API.
Wix is a set of wrapper libraries around msi.dll. Less MSIErables wraps the whole mess.) The latest.Net Framework is about 500 MB! Neither.Net nor Wix is necessary for processing MSI files, so unless you already have.Net and Wix installed, Less MSIErables will add a big pile of bloat to your system for no reason. • Universal Extractor - Universal Extractor is useful for unpacking some installer files, but it is actually just a convenient wrapper around a number of other unpacking tools. It works well with some types of installers and not so well with others. At last count Universal Extractor had 3 different methods to unpack MSI files and none of them actually worked. Caution: Universal Extractor development was discontinued with version 1.6.
More recently, a Russian author has been releasing an 'unofficial' updated version. The Russian version does not appear to be malware, but it is suspicious. First, the installer is encrypted and password protected.
So it's an installer for an installer unpacker which is, itself, impossible to unpack! Second, the Russian version is using JSWare MSI unpacker files without notification to us and without permission. Those files have also been altered significantly. Third, the new version also offers to unpack MSIs using MsiX or 7-Zip. As explained below, those do not work. The Russian author clearly does not understand the software he's using. As with the original version of UE, at best the new version is just a repackaging of software from other sources.
We do not recommend running the installer for the 'unofficial' version (post 1.6.1) of Universal Extractor. • 7-Zip - Many people mistakenly believe that the free compression program 7-Zip can unpack MSI files. Even the says so. 7-Zip cannot unpack MSI files. Technically, 7-Zip can extract content from MSI files.
If you open an MSI file with 7-Zip it will appear to show you the content, but what you'll see are binary versions of the database tables, along with internal resources such as icons displayed during installation. None of those items are of any particular value. It's analogous to dismantling a car by cutting it into slices. The slices do represent parts of the car, but they are not relevant parts. If the MSI contains a CAB file, 7-Zip can be used to extract that from the MSI, but then all you have is a CAB full of files with incorrect names, because part of the silliness of MSI installers is that, 'by tradition', program files in the package are always given nonsense names. The only way to find the correct names and install paths of files in an MSI CAB is through a circuitous cross-referencing of multiple MSI database tables. That's what an MSI unpacker does.
So the seeming ability of 7-Zip to unpack MSI files (or any compound storage file format, such as DOC and PPT) is just a source of confusion with little or no value. (See the above for more info.) • MsiX - Some people think that MsiX is an MSI unpacker. It is a small command-line utility for working with embedded binary files in an MSI or an MSP patch file.
MsiX can extract resources such as BMPs, ICOs, etc. From the _Streams table, and it can extract items from the _Storage table. In general these items are not relevant except to the author of the installer. And the latter table is generally only relevant with MSP files. If you want to extract resources see.
Extracting all files from the _Streams table is a simple operation in script. Of all the options above, Less MSIErables is the only one that can really unpack an MSI and put the extracted files into a folder tree that represents how the program will be configured if you install it. Overvaluing Open Source: It is notable that the programs listed above are all so-called 'open source software' (OSS). There is a strong tendency among many people to idealize OSS.
OSS has developed into somewhat of a club, such that it may sometimes be recommended even when it can't do the job required, simply because OSS followers are not aware of anything except OSS. Even apparent experts at sites such as and make that mistake. (Both sites mistakenly list 7-Zip as an MSI extractor tool.) Basically, OSS means that the software's source code is available. That can be helpful to programmers, but most people can't use or read the source code. And in many cases the source code is not particularly useful. In the cases of Less MSIErables and Universal Extractor, for example, both are lightweight wrappers around other software, so their source code doesn't provide anything much of value. ( 7-Zip, by contrast, is a very capable and highly regarded program.
It just doesn't happen to work for unpacking MSIs.) For anyone who wants 'source code', the VBScript unpackers here offer more complete source code than any other tools available. As script, all the code is in plain text. Anyone is free to reuse that code as they like. The scripts come with an extra, small program required to extract from CAB files, but the actual processing of MSI files is done entirely through MSI.DLL (the basic Windows Installer library) with VBScript. Using MSI.DLL is the most direct method. It is Windows Installer.
There is no need for bloated extra dependencies such as.Net, Wix, or 3rd-party software. For interested programmers there is a Windows Installer help file as part of the Windows SDK. That documents the two sets of methods for processing MSI files: The COM automation object model using WindowsInstaller.Installer and the Win32 functions. The JSWare tools here either demonstrate the COM automation objects (VBScript and HTA) or use the Win32 functions (jsMSI.dll, jsMSIOps.exe and jsmsix.exe). If you have sample script code it's not difficult to go from there to the Win32 API functions in MSI.DLL. That is, once you know about how MSIs work and how the Windows Installer object model works, the API versions of the same methods are fairly self-explanatory. MBase - MSI Database Editor The MBase MSI Editor is a database editor program, created as a webpage.
More specifically, it's an HTA program. (If you don't know what that is,.) The editor can display the content of MSI files and allows you to add or remove tables, rows and columns. You can also edit individual row cells, export the text of specific tables or all tables, and export, insert, or overwrite embedded MSI CAB file data streams. All through a convenient graphical interface (Embedded CABs are the most common way to store the actual software files in an MSI/MSM installer file.) MBase can be used to work with MSI software installation files, but it's designed to be more adaptable than that. It can also be used to create your own databases from MSI files, designing the tables for your own specific needs rather than using the standard MSI tables. (See the ZipFinder sample below.) MBase can also be used to adjust poorly designed software installers. Example: As mentioned in the introduction above, a surprising number of software installers insist on having a specific version of Internet Explorer, even though they don't actually require a browser at all.
Hewlett Packard printer software is one example of that. (Actually, much of the software and many of the driver installers that come with PC hardware seem to be slipshod productions done on a tight budget. HP is not alone. But writing a printer driver installer that requires a specific browser version is inexcusable stupidity that never should have made it into the final product.) A nonsensical IE requirement is especially a problem because updating Internet Explorer is a tricky business that can often go wrong. IE version requirements and other similar installation problems can often be bypassed with MBase. If the software is installed via MSI, you can just open to the LaunchCondition table to check for installation requirements, and change MinVersion / MaxVersion fields in the Signature table to alter install requirements. (Or even better, just remove all rows from the LaunchCondition and/or InstallCondition tables, if they exist, in order to remove installation restrictions.) Of course, that won't make software run on Windows 98 if it was written only for Windows NT systems, but it may at least save you from wasting unnecessary time with badly designed MSI installers.
Note The MSI Editor will also work with the component, allowing MSI files to be opened in the editor by dropping them onto the MSI Editor program file or its shortcut. Compatibility note: The MSI-MSM Unpacker should display and function well on all Windows versions from Windows 95, with any version of Internet Explorer from 5 up. If you find any dysfunctionality, about differences in IE versions and Windows versions. ZipFinder Zip Code and Area Code Database Program ZipFinder is a webpage program that uses an MSI database file to hold and access approximately 55,000 US zip codes and most area codes. You can enter city/state names to return a zip code, or enter a zip code to return the respective city and state. You can also enter an area code to find its location. ZipFinder does not require any knowledge of script or webpages.
Just download the zcodes.zip file and extract the contents. You will have a folder named 'ZipFind'.
Put the folder anywhere, then create a shortcut on the Desktop going to the ZipFinder.hta file inside the ZipFind folder. Double-click the shortcut to find zip code and area code information.
(Note to scripters/programmers: ZipFinder is designed to be an easy-to-use utility, but it also constitutes a sample program demonstrating the use of MSI files as SQL databases. The download comes with a copy of a VBScript class for working with MSI SQL functions, and it includes a copy of the script that was used to create the zip code database.) Script to Edit MSI Files: Change installer window appearance and add information This is a single VBScript that can do two things: 1) Change the background picture in an MSI installer 'welcome dialogue' window. (The window that shows first when you install software from an MSI file.) 2) Add custom notes and a list of file versions to the welcome dialogue window of an MSI file. Adding custom notes provides a way to conveniently store installation information in an MSI file. For example, you might save information about date installed, or info.
About problems you had with incompatible programs, or the URL of drivers that you'll need when you install this package, etc. What the custom notes function does is to first add a scrolling text box (actually a 'RichEdit' control) to the upper left of an installer's 'Welcome dialogue' or splash screen window (provided that the installer includes a 'welcome dialogue'). It then provides an option to permanently store your custom notes text in the text window. Third, it searches the MSI for files with version numbers, such as EXE and DLL files.
Then it adds a list of those files, along with their version numbers, to the same RichEdit text window. The result is that when you open the MSI file later, the first window shown will contain any notes that you chose to save, and you will have the opportunity to check what versions of which system files the installer is likely to change on your system.
In other words, the text window serves as your own, custom 'README' file, built into the installer itself. JsMSI.dll and jsMSIOps.exe - A Component for MSI Programming jsMSI.dll is a component that provides the functionality of the 1-click unpacker and the MBase MSI class in a compiled library. JsMSIOps.exe is the exact same thing, but compiled as an ActiveX EXE, which allows it to run on 64-bit Windows without complications. JsMSI.dll/jsMSIOps.exe provides a simplified API, for both script and compiled software. It wraps the awkward and error-prone SQL syntax of Windows Installer, as well as the unnecessary abstruseness of the overall design, providing simple, straightforward Win32-style functions instead: ImportTable, RemoveTable, GetValue, SetValue, AddRecord, RemoveRecord, etc. Example: AddRecord('TableName', 'Column1Value, Column2Value, Column3Value, Column4Value') jsMSI does not really add anything that can't be done with the various JSWare scripts and HTAs. It just uses the more efficient Windows Installer API and wraps the whole thing in a single neat package.
There are almost 50 functions here. No SQL needed. No superfluous XML nonsense. No need to deal with the verbose code mess of getting View objects, looping through Record objects, etc. JsMSI also includes built-in CAB operations. Sample scripts in the download include a basic unpacker, demonstrations of getting and setting table values, demos of adding and removing tables and records, and a drag-drop script that combines several jsMSI operations to replace a given file in an installer package.
(Find the file, extract the CAB, rebuild the CAB using the new file, re-insert the CAB in the MSI, and update the File table.) Requirements and Notes: jsMSI.dll should run without problems on Win98/2000/ME/XP/2003/Vista/7/8. But on Vista/7/8 there may be issues connected with default permissions settings. If you have any problems with jsMSI.dll on Vista/7/8, please be sure that you have ruled out problems with Vista/7/8 permissions before writing to JSWare for help. These components should also run without problems on Windows 10, but have not been tested. For 32-bit Windows or 32-bit software on Win64: For all 32-bit or 64-bit configurations: Replacing a File Inside an MSI A significant number of people end up at this webpage because they want to replace a specific file within an MSI.
In other words, they want to leave an installer intact but replace or update one file inside the installer. That typically requires extracting the CAB file, extracting the CAB contents, building a new CAB, and replacing the CAB into the MSI. Additionally, there will usually be at least one or two edits required in the MSI database to update the file size, perhaps file version, etc. There is not actually a separate tool here for doing the job of replacing a file, but the includes a sample script to do the job. The comments at the top of the script explain the details. Download jsMSI.DLL, look in the sample scripts folder, and find the script named ReplaceCABFile.vbs. (Note: The file-replacer script is written to work with an MSI that contains a single CAB.
In the case of a very large installer that contains spanning CABs, the script would need to be edited, adding a step to identify the relevant CAB file.) Extracting MSI Resources This is not useful for most people, but some may be interested. The script here extracts binary resources from an MSI. Resources are not program files. They are binary files, such as bitmaps, icons, or embedded DLLs and EXEs, used by the installer itself during setup. Geo-location Database This is a perfect example of how useful the simplicity and efficiency of MSI databases can be. It uses an MSI to hold geo-location data, for translating IP addresses to their location. Example: 198.203.177.177 Plymouth-MN-US This product includes GeoLite2 data created by MaxMind, available from.
MaxMind is a company that creates and sells geo-location tools. They have a free version of their worldwide IP-to-city database. The scripts in this download can be used to convert the MaxMind CSV files to MSI tables, which are then imported into an MSI file. There are nearly 3 million entries in the IP table and nearly 100,000 in the location table, yet a query to get the location of an IP address is almost instant. The download includes detailed instructions and also includes sample code for querying the database. Email Base - MSI Database For Email Backup Another handy use for MSI database files.
This is an HTA program that serves as a program to fill MSI files with email for backup, then easily and quickly access, search, read, or extract attachments from those emails. You can store as many MSIs as desired: One for each year's email, one per account, etc. For more info and a screenshot see the download page description. CodeLib Code Storage Database Codelib is a code library database for storing code samples, snippets, type libraries, etc.
It uses an HTA with an MSI file 'backend' to provide a searchable, organized storage system. Use it to store large files or small snippets. For further information about CodeLib see the. MSI-SQL VBScript Class with Documentation The MBase MSI Editor and the ZipFinder utility both come with a VBScript class for working with MSI databases. This download is that class plus documentation about how to use it.
The MBase class provides a number of functions for working with MSI databases. It provides several functions specific to MSI, and it also provides a number of SQL-related functions. With the MBase class there is no need to construct SQL query strings. Instead, the SQL calls can be made like standard Windows API functions. For example, the function: GetSelectValues(TableName, ColumnName, ColumnToCompare, ValueToCompare) will return an array of all values in a given table column, where the value in ColumnToCompare matches ValueToCompare. In other words, the MBase class lets you use the basic functionality of an MSI database without needing to learn SQL query language, and without having to fiddle around with the tedium of composing query strings with compound nested quotes.
Technical Notes Regarding IE7+ and Windows Vista/7+ Internet Explorer 7+ You should not have any problems using the JSWare HTA tools with any version of Internet Explorer later than IE4. The MSI tools here that use Internet Explorer windows (combined with VBScript and the IE Document Object Model) are HTAs. They have been written using IE5 or IE6.
They have been tested with IE5, IE6, and to some extent with IE8. All of these HTAs are written in what Microsoft calls 'quirks mode'. That means that they should look and act almost identically in any version of IE. You should not have any problems. However, Microsoft has broken compatibility with each version of IE and quirks mode may not be perfect when dealing with the complex webpage functionality needed for the JSWare MSI tools. If you have any problem (for instance, the program interface not fitting properly into the window) then see the help for tips. You can also send an email if you like.
(Please describe the exact problem, the Windows version and the IE version with any such bug reports.) Windows Vista/7/8 The MSI tools here should work without any special requirements on Windows 95/NT4/98/2000/ME/XP/Vista/7/8, provided that the installed version of Internet Explorer is at least v. However, Windows Vista/7/8 is designed with complicated restrictions that can cause problems with any software. If you have any problems with these MSI tools, please feel free to write. But please do not write asking for help about permissions, security, so-called 'virtualization' issues (whereby Windows blocks you from accessing a file but pretends otherwise) or any of the other problems specific to Windows Vista/7/8 restrictions. The MSI tools here should work without problem on Windows 8, but none of them will work in the Metro tile window. Metro is an entirely new, restricted 'sandbox' system, designed for running 'swipe and smudge' trinket apps and games used on tablets and phones. Metro tile buttons are the new interface for Microsoft online services (one could think of it as the AOL walled garden for highspeed), which Microsoft is trying to market by imposing the Metro screen on Windows 8 PCs.
To use normal Windows software on Windows 8 one must hide the Metro interface and work in 'Windows mode' with the normal Desktop interface. Vista/7/8 Security Problems Windows Vista/7/8 really only comes in one basic version. The differences between versions are differences in what 'features' are included, not in the product design. All versions, including the Home versions, are designed to function as corporate workstation PCs, with limited rights granted to the person using the PC.
The person who installs the system is what might be termed a 'fake administrator'. A fake administrator is an oxymoronic status that Microsoft cooked up with Windows Vista. That person has the status of being in the Administrator's group, but without Administrator rights. (The difference between a fake administrator and a common 'user', is that the fake administrator will be shown nag windows in some cases, giving them the possibility to 'elevate' their rights for a single operation.) Fake admin.
Status can result in numerous problems and confusion when trying to run software or access files. A fake admin. Account normally has very few rights, so you may have trouble using the various MSI utilities.
A notable example of the problems created by Vista/7/8 security limitations is that without full admin. Rights you cannot drag-drop a file onto a VBScript (.vbs file). The VBScript requires admin.
Rights to run, and there is no way to get those rights in a drag-drop operation. So the Simple 'One-Click' Unpacker is not so simple on Vista/7/8.
Without admin. Rights it can only be used from the Run window or a command prompt. If you want to have free reign to do as you like on your PC -- like you probably had in the past with Windows /ME/XP -- you need to activate and use the only real Admin. Account available on Vista/7/8. To do that, open a command prompt using the 'Run as Administrator' option. If your fake Admin. Account has a password then type: Net user administrator password where 'password' is your account password.
Then type: Net user administrator /active:yes and press Enter. After rebooting, the 'Administrator' account, which is a real administrator, will be active and will show at the login screen. You can then adopt the 'Administrator' account as your normal login and be done with the Vista/7/8 restriction hassles.
If you ever want to remove the Administrator login option, just type the following in the Run box: Net user administrator /active:no A Note to Non-Technical People Some people may have arrived at this webpage because they want to just see inside a.msi file, or want to know what the file extension.msi means. The short explanation of that is that an MSI file is used to install Windows software. Some software comes in an EXE file.
Some comes in an MSI file. And sometimes it's an MSI inside an EXE. A software installer file, whether MSI or EXE, generally contains all of the files for the given software program. It also contains some method to copy those files out, create shortcuts on the Start Menu, etc.
If you are here because you would like to inspect the contents of an MSI file before installing, you probably want. With that you can simply browse for an MSI file and click a button to have it unpacked. What are 'HTA webpage programs' and what do I do with the downloaded.zip file? Most of the downloads here are not 'normal' software programs. They are actually composed of webpages and/or script. (Script just refers to executable programming language that is in the form of text rather than being compiled into an EXE file.
Script is what allows webpages to be interactive.) Some of these programs run in an Internet Explorer window. The method is similar to the way that webpages online can be interactive. But a webpage offline, running on your own PC, can do much more. (In other words, the MSI webpage utilities are like the famous 'cloud' Internet-based programs that everyone keeps talking about. But they have the added advantage of not being in 'the cloud'. They reside on your own PC, even though they run in a browser.
So they avoid the limited functionality and security problems of 'cloud computing'.) An HTA file is just a webpage file designed to run as an interactive program in Internet Explorer. For all practical purposes, an HTA program is just a webpage in Internet Explorer that is not limited by the restrictions needed for online security. The fullscale MSI Unpacker and the MBase MSI Editor (above) are both HTA programs. They work in much the same way as a normal program, but they are actually composed of webpage code (HTML/CSS) and script code (VBScript).
Designing the programs that way is easier than creating a 'normal' program with an EXE file. Using an HTA also means that everyone can read and edit the code that actually makes the program work. Control4 Driver Wizard. So people who know how to script can add their own functions or changes to the code. At the same time, a 'webpage program' is not necessarily limited in its functionality.
The MBase MSI Editor (above) is comparable in functionality to the 'official' Microsoft MSI editor, named Orca. (The big difference is that with the MBase MSI editor you don't have to register with Microsoft, download gigantic chunks of the Windows SDK, or allow the installation of Microsoft's WGA spyware in order to get the program.) The downloads here do not install like a typical program. Rather, each download is a ZIP file containing a compressed folder full of files. To use the downloads, open the.zip file and take out the main folder.
If you do not have a program to handle ZIP files then when you double-click the ZIP file download it will probably appear to open as a normal folder window. In that case, to remove the folder full of files from the ZIP file, just drag it out of that window and onto the Desktop. Then close the 'fake folder window'. Each download has an information.txt file in the main folder that provides basic instructions. Norton says these files might be dangerous!' You might get a security warning from anti-virus software when you use the downloads here. VBScript and HTA files are mainly used by network administrators, programmers, etc.
The average PC user does not know about them. At the same time, anti-virus programs are fairly simple and 'dimwitted', on the lookout for 'unlikely' behavior. Therefore, some anti-virus programs have been designed to be suspicious when any.hta or.vbs file runs, on the presumption that it might be a virus file downloaded in email. If you see a warning from anti-virus programs you will need to select the option to 'Allow this script to run.'
Anti-virus software might also flag JSWare EXE files. In one case, Avira anti-virus tagged the JSWare MSI unpacker as 'generic' malware.
In tests it also tagged 6 of our other EXE files as the same malware! Attempts at communication with the Avira people to point out their error only resulted in useless, 'thank you for your interest', robo-email responses. The EXEs had to be recompiled until Avira stopped complaining! Avira may not be worse than other companies. They're producing an outdated product that most people are unwilling to pay for, so it's not surprising that their product is limited in its efficiency and that their customer support is non-existent. If you find any problems with anti-virus or 'anti-malware' tools complaining about JSWare software, feel free to with the details.
We can probably fix the problem. Update History General changes are explained here. See the downloads for more specific update notes. The most recent updates to tools here were in 2014. The general functionality hasn't changed much with various updates, but some updates have been necessary to come up with methods suitable for use with faulty MSI files. There are numerous rules related to how an MSI can be built.
Oddly, the people who make the faulty ones seem to be the people who should know better. We have come across two faulty MSIs in the past that the JSWare tools failed to unpack properly. One was part of Microsoft's Network Monitor package. (NetworkMonitor_Parsers.msi) The other was created by a well known coding expert and Microsoft MVP.
Both required changes to the JSWare tools to work around errors in the MSI structure. (Technical details are in the downloads.) If you come across an MSI that JSWare tools cannot unpack, feel free to with a link to the MSI. We should be able to determine the problem. Related Update News The HTA tools (MSI Editor and MSI/MSM Unpacker) work with the component. If you install JSDrop it can be used to customize HTA file drag/drop (or any other kind of file). The HTA 'scripting object' also has a commandLine property. Yet HTAs do not normally have what's known as a 'drop handler', so dropping files onto them doesn't work.
By using JSDrop one can drag/drop files onto any HTA and process the command line as one might with a VBS file. JSDrop is a free component for use on 32-bit Windows systems.
