I have included in this addon package the innounp GUI package written by Richard Santaella and also added some reg entries for those of you who want the option to directly extract to a sub-folder from your shell menu, which are based on nullz's scripts at the SourceForge forums here.
Please note that this addon package is purely experimental at this stage, but it seems to be working AOK for me in my Win2k3 here. Also note that, being experimental, I may decide to abandon it at any time in the future - so what you see is what you get (for now)

Enjoy.... or not....innounp, the Inno Setup Unpacker
Innounp is an open source console application based on IS source, and it uses command-line options to find out what to do. It recovers portions of the installation script (.iss file), including the registry changes and the compiled Innerfuse/RemObjects Pascal Script, if available. The current version supports Inno Setup versions 3.0.0-beta through 5.1.10.
