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) 

Extract Files From Nullsoft Installer Posted on 3/21/2018 by admin Advertisement What do you do when you’ve created some new Windows software — anything from a Every Windows user eventually encounters problems that aren't easy to diagnose. Install 7-Zip, for instance, and you’ll be able to right-click Windows Installer files (.MSI) and extract their contents. This only gets you the source files, so there’s no information on.

 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.

Older versions are still available for download.
 There is also a port of innoextract to Android by Alan Woolley.

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 innoextract
Compatibility
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. 
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.
 Another (Windows-only) tool to extract Inno Setup files is innounp.

Remarks
NSIS (Nullsoft Scriptable Install System) is a professional open source system to create Windows installers. It is designed to be as small and flexible as possible and is therefore very suitable for internet distribution.
Being a user's first experience with your product, a stable and reliable installer is an important component of succesful software. With NSIS you can create such installers that are capable of doing everything that is needed to setup your software.
NSIS is script-based and allows you to create the logic to handle even the most complex installation tasks. Many plug-ins and scripts are already available: you can create web installers, communicate with Windows and other software components, install or update shared components and more.
