WiX Toolset
Open-source toolset for building Windows installation packages (MSI/MSIX) from XML source.
Our Verdict
When you need real MSI/MSIX and enterprise deployment, WiX is still the right answer — just budget the ramp-up.
Pros
- The standard for serious Windows MSI/MSIX installers
- XML-authored, diffable, CI-friendly
- Open-source with active v5 development
- Full access to Windows Installer features
Cons
- XML authoring has a steep learning curve
- Error messages are famously inscrutable
- Licensing/sponsorship story shifted in recent years
- Overkill for simple EXE installers
Best for: Enterprise Windows apps requiring MSI/MSIX and Group Policy deployment.
Not for: Indie apps where Inno Setup or Velopack are vastly simpler.
