## What it is
innoextract is a command-line tool that extracts files from installers created by Inno Setup, without running the installer under Windows or Wine. It supports Inno Setup 1.2.10 through 6.3.3, including modified variants like GOG.com game installers, and is written in C++ with Boost and liblzma dependencies.

## Use cases
- extract inno setup installer on linux
- unpack gog game installer without wine
- list contents of a setup.exe
- verify checksums of installer files
- extract windows installer files on mac
- get gog game id from installer

## When to choose
- you need to extract Inno Setup installers on Linux, macOS, or other non-Windows systems
- you want to inspect or verify installer contents without executing the setup executable
- you need to unpack GOG.com or other modified Inno Setup installers

## When to avoid
- you need to extract installers made with other tools like NSIS or MSI
- you need a GUI extraction tool
- you need to create Inno Setup installers rather than extract them
