Inno Setup

Free installer for Windows programs by Jordan Russell — script-driven with a mature, stable UI.

-
AU Est. 1997 Active CI/CD for Applications

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
  • Custom install UI with registry and file operations
  • Silent installation mode for enterprise MSI-free deploys
  • Digitally sign Windows installers in automated pipelines
