Inno Setup
Free installer for Windows programs by Jordan Russell — script-driven with a mature, stable UI.
Our Verdict
The safe, boring, works-forever Windows installer — unbeatable if you don't need MSIX.
Pros
- Battle-tested Windows installer used by thousands of apps
- Mature Pascal scripting with deep customization
- Small installer footprint
- Free for commercial use
Cons
- Pascal scripting is niche and off-putting
- No MSIX output, only classic EXE installers
- UI feels very Windows-98 by default
- Single maintainer project, slow release cadence
Best for: Shipping classic Win32 desktop apps with a traditional installer wizard.
Not for: Teams that need MSIX, Store submission, or modern cross-platform tooling.
When to Use Inno Setup
Good fit if you need
- Script-driven Windows installer creation for desktop apps
