Innounp, the Inno Setup Unpacker

Inno Setup is a popular program for making software installations. Unfortunately, there is no official unpacker - the only method of getting the files out of the self-extracting executable is to run it.

* Innounpis open source and based on IS source. Therefore, it is more likely to support future IS versions.
* It recovers portions of the installation script (.iss file), including the registry changes and the compiled Innerfuse/RemObjects Pascal Script, if available.

Innounp is a console application, and it uses command-line options to find out what to do. For a more human-friendly interface utilizing FAR or Total Commander as a front-end see the MultiArc section below. Windows Explorer fans: nullz has made some .reg scripts to add innounp into the right-click menu and Richard Santaella crafted a graphical wrapper for innounp (get it on the download page).
