Innounp is a free open source command line tool that extracts files from Inno Setup installers without running the installation. It allows you to unpack executable setup files and access their contents safely, making it useful for analysis, file recovery, or creating portable applications.
Innounp is a command line extractor designed to unpack Inno Setup based installers, allowing you to view and extract files without installing the program.
What is Innounp?
This lightweight utility is designed to reverse the Inno Setup packaging process and extract the files contained within a setup executable. Instead of launching an installer, you can safely inspect and retrieve its contents.
Because it runs entirely from the command line, it is especially useful for advanced users, developers, and anyone interested in portable software.
How It Works
The tool reads an Inno Setup installer and extracts embedded files directly to a folder of your choice, without modifying your system.
- Place the executable in the same folder as the installer
- Open Command Prompt in that directory
- Run a command to list or extract files
- Access the unpacked files instantly
Common Use Cases
- Extract files without installing software
- Inspect installer contents for safety or analysis
- Create portable versions of applications
- Recover files from older or archived installers
