Inno Setup
What Inno Setup is
Inno Setup is an open-source builder for Windows application installers, introduced in 1997 by Jordan Russell and Martijn Laan. It can create a single EXE for online distribution or split an installer across disks. Installer features include file compression, version comparisons, replacing files in use, registering DLLs and type libraries, downloading and verifying files, and extracting archives. A preprocessor supports compile-time customization, while an optional Pascal scripting engine can customize installation and uninstallation at runtime. Installers can be password-protected, encrypted, and digitally signed; uninstallers can also be signed. The software supports x64 and Arm64 applications on 64-bit Windows editions, and Windows releases since 2006, including Windows 10, Windows 11, and listed Windows Server editions. Its download page offers 32-bit and 64-bit editions, each able to build 32-bit or 64-bit installers. The maker says it works offline and sends no data for updates, license checks, statistics, or other purposes. The forum is the primary support source.
