MSI Unpacker is a basic tool which can extract the contents from Microsoft Installer files. In essence, it isn't very dissimilar from archivers like Winzip or 7Zip.
Once you have the application running, its user interface involves opening an MSI file from your system, selecting a location for save the contents of the extraction and hitting the 'Unpack' button.
InnoExtractor 5.4.5.202 is available to all software users as a free download for Windows 10 PCs but also without a hitch on Windows 7 and Windows 8. Compatibility with this unpack installer software may vary, but will generally run fine under Microsoft Windows 10, Windows 8, Windows 8.1, Windows 7, Windows Vista and Windows XP on either a 32. Download this app from Microsoft Store for Windows 10, Windows 8.1. See screenshots, read the latest customer reviews, and compare ratings for Unpacker. Download p7zip for Linux (Posix) (x86 binaries and source code): p7zip at SourceForge p7zip is the command line version of 7-Zip for Linux / Unix, made by an independent developer.
The procedure takes a little bit of time depending on your system, and once complete, files from the MSI file will be accessible from Windows Explorer inside the folder specified in 'Save Location'.
MSI Unpacker is completely portable and thus can be run from a USB stick or from anywhere else. It leaves no registry entries.
Apart from that, MSI Unpacker provides no other functionality and thus is not difficult to use or understand. Overall, it completes its singular task and is thus useful for anybody wishing to extract the contents of a Windows Installer file.
MSI Unpacker on 32-bit and 64-bit PCs
This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from file archivers without restrictions. MSI Unpacker 1.5 is available to all software users as a free download for Windows 10 PCs but also without a hitch on Windows 7 and Windows 8.
Compatibility with this software may vary, but will generally run fine under Microsoft Windows 10, Windows 8, Windows 8.1, Windows 7, Windows Vista and Windows XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Free Softworks.

About
Inno Setup is a tool to create installers for Microsoft Windows applications. innoextract allows to extract such installers without running the actual setup executable under Windows or using Wine. innoextract currently supports installers created by Inno Setup 1.2.10 to 6.1.2. (details)

In addition to standard Inno Setup installers, innoextract also supports some modified Inno Setup variants including Martijn Laan's My Inno Setup Extensions 1.3.10 to 3.0.6.1 as well as GOG.com's Inno Setup-based game installers. innoextract is able to unpack Wadjet Eye Games installers (to play with AGS), Arx Fatalis patches (for use with Arx Libertatis) as well as various other Inno Setup executables. See the list of limitations below.
While developed on Linux, innoextract is cross-platform and meant to work with any C++03 to C++17 compiler, architecture and operating system supported by CMake, Boost, liblzma and (optionally) iconv.

Usage
To extract a setup file to the current directory run:
$ innoextract <file>A list of available options can be retrieved using
$ innoextract --helpDocumentation is also available as a man page:
$ man 1 innoextractCompatibility
innoextract cannot guarantee good forward compatibility as the Inno Setup data format changes frequently. The following table lists the supported versions:
| innoextract 1.9or newer | Inno Setup 1.2.10 to 6.1.2 |
| innoextract 1.8 | Inno Setup 1.2.10 to 6.0.5 |
| innoextract 1.7 | Inno Setup 1.2.10* to 5.6.1 |
| innoextract 1.6 | Inno Setup 1.2.10* to 5.5.9 |
| innoextract 1.5 | Inno Setup 1.2.10* to 5.5.6 |
| innoextract 1.3 to 1.4 | Inno Setup 1.2.10* to 5.5.5 |
| innoextract 1.0 to 1.2 | Inno Setup 1.2.10* to 5.4.3 |
innoextract 1.7 and older cannot extract installers created by Inno Setup 1.3.0 to 1.3.23. GOG.com Installers
GOG.com installers with a 2.x.x version number on the download page or in the filename use Inno Setup 5.5.0 and cannot be extracted by innoextract 1.2 and older. Older installers use Inno Setup 5.2.3 and usually have no version in the filename.
Some GOG.com multi-part installers with version 2.1.x or higher use RAR archives (renamed to .bin) to store the game data. These files are not part of the Inno Setup installer. However, innoextract 1.5 or newer can extract them using the --gog option if either unrar or unar is installed.
Other newer GOG.com installers don't include the raw files directly but instead store them in GOG Galaxy format: split into small parts which are then individually compressed. These files are named after their MD5 hash and stored in the tmp directory, for example 'tmp/ab/d7/abd72c0dddc45f2ce6098ce3a286066a'. innoextract 1.7 or newer will automatically re-assemble these parts and extract the original files unless the --no-gog-galaxy option is used.
Pipe Unpacker Zip
Some multi-part GOG.com installers use .bin slice files larger than 2 GiB - extracting these requires innoextract 1.8 or newer on 32-bit platforms. Older versions failed with a 'bad chunk magic' error.
Limitations
- There is no support for extracting individual components and limited support for filtering by name.
- Included scripts and checks are not executed.
- The mapping from Inno Setup constants like the application directory to subdirectories is hard-coded.
- Names for data slice/disk files in multi-file installers must follow the standard naming scheme.
Also see the list of planned/requested enhancements on the issue tracker.
Free Rar Unpacker
Another (Windows-only) tool to extract Inno Setup files is innounp.
