How does it work? When you use the Inno Setup compiler, you write a script that defines how your installer should behave. This script can specify files to include, registry entries, shortcuts, and even custom dialogs. The compiler then generates a single executable installer file.

The Inno Setup installer works by guiding users through a familiar setup wizard. It extracts files, places them in the correct directories, and creates shortcuts. Developers can also use Pascal scripting to add advanced logic, making the installer highly customizable.

What’s new in the 2025 update? The Inno Setup 2025 update introduces:

Windows 11 Optimization: Full compatibility with the latest OS features.

Enhanced Pascal Scripting: More functions and libraries for advanced customization.
