[ZyntaXis de Havysoft]

Hello everyone,

I decided to open this topic to show the Inno Setup community my project that I've been working on for many years, and also in case you find it useful, called InnoExtractor, a powerful unpacker and forensic app for Inno Setup-based installers. It allows you to open, examine, inspect, extract and more the files and internal content of installers (also known as "setups"), without having to start/run the installation wizard.
