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. One piece of software that addresses this issue is Sergei Wanin's InstallExplorer, a plug-in for the FAR Manager that unpacks several types of installations, including Inno Setup (IS). Actually, innounp was made during the period when InstallExplorer was not updated, and was meant to replace it. Now that a new version is out, innounp still has some useful features:
It is open source and it is based on IS source. Therefore, it is more likely to support future IS versions.
It recovers part of the installation script (.iss file), including the registry changes, and the compiled Innerfuse/RemObjects Pascal Script, if available.
