WiX Toolset by the numbers

The most powerful set of tools available to create your Windows installers

11M+ installs and counting

Our tools build the most installers

Downloaded more than 11 million times since we started counting in 2015, the WiX Toolset is the most popular tool for creating Windows installers. HeatWave brings the power of WiX to Visual Studio and your product's installer, too.

25+ years as open source

An Open Source pioneer in the .NET ecosystem

The WiX Toolset was released as an Open Source project in 2004. It was Microsoft's first Open Source project and led the way for many more. Through it all, Rob Mensching has led the project bringing the most powerful set of Windows installer tools to the world.

It's all code

WiX fits naturally into the software development process. Rather than relying on proprietary binary files, WiX uses XML text files for seamless integration into any source control and build system.
  • View and edit installer source code with any text editor.
  • Easily track changes in the installer source code in source control.
  • Merge changes simply and intuitively.

Clean, compact, correct

WiX is the only installer technology that provides complete control of the resulting Windows Installer packages.
  • WiX enables the full capabilities of the underlying Windows Installer platform.
  • You can control exactly what goes into your packages because WiX adds only what's required to each generated MSI.
  • Features like smart cabbing ensure the most compact output by removing duplicate files from cabinet files.

Beyond the Windows Installer

WiX is far more than a thin veneer on top of the Windows Installer. The Burn bootstrapper engine lets you create rich UI experiences with familiar and powerful technologies like WinForms and WPF.
  • Bundles let you have a single installation experience from many packages in your product and its prerequisites.
  • The Burn engine does the heavy lifting when building highly customized user experiences.
  • Packages can be downloaded on demand from the Internet, to minimize the installer size.
  • Add-on bundles allow for easy integration of out-of-band product releases into the original installer.
