Innounp is a command line setup unpacker. It allows a user to unpack a program without installing the program on the Windows PC. It can be used specifically to extract application files from executable .exe files originally created using the Inno Setup Installer. This is a great way to begin making portable applications from Inno Setup created executable installers.
Innounp Commands and Options
Firstly, note that this tool runs from a command window. You can run from the directory that also contains the executable you plan to extract. After that, using the Inno Setup Extractor is easy. Simply use the following section of commands to get started. This list of commands and arguments was quoted from the authors site.
