innounp, the Inno Setup Unpacker
Version 0.04. Initial release.
Supports Inno Setup versions 4.0.1-beta through 4.1.8.

Inno Setup is a popular program for making software installations. Unfortunately, it is one way - once made, there is no official method of getting the files from the self-extracting executable other than running it. One piece of software that addresses this issue is InstallExplorer, a plug-in for the FAR Manager that unpacks several types of installations, including those made by some older versions of Inno Setup (IS). It is no longer updated, and it does not work for IS versions 4.x.

Innounp is a little different: it is open source and it is based on IS source. Therefore, it is more likely to support future IS versions.

If you want to report a bug, request a feature, or discuss anything else related to the program, please write to the forums.

Usage

Innounp is a console aplication and it uses command-line options to find out what to do.

innounp [command] [options] setup-name.exe [filemask ...]
Commands:
  -l list the files in the installation
  -x extract the files from the installation to the current directory
Options:
  -q extract files quietly
  -e extract embedded files (such as decompressor.dll and uninstall.exe)

Both the source and the executable distributions are packed with WinRar. Get it from http://www.rarlab.com, you will probably need at least version 3. While the full-featured compressor is shareware, the UnRar utility that can only extract files is free.
