What is Windows Installer XML?
Windows Installer XML (WiX) is an open-source toolset that builds Windows Installer packages from XML source files. Originally developed inside Microsoft and released as open source in 2004, it compiles .wxs XML definitions into .msi, .msm, and related Windows Installer output formats. It is widely used by software developers to create professional, scriptable Windows installation packages.
