Innounp – The Inno Setup Unpacker

Innounp is a command line setup unpacker. It allows a user to unpack a program without installing the program on the Windows PC. Innounp can be used to extract application files directly from an .exe file that was created using the Inno Setup Installer. It’s a great way to begin making portable applications from Inno Setup created executable installers.

Innounp Commands and Options:

Innounp is run from a command window. It is easiest to run it from the directory containing the executable program your going to extract. The complete list of commands and arguments are shown below as quoted from the authors site.
