About WiX
Windows Installer XML, or WiX, provides a schema that describes a Windows Installer database (MSI or MSM), as well as tools to convert the XML description files into a usable database. The WiX tools model the traditional compile and link model used to create executables from source code. This section provides an introduction on the tools and concepts as well as an overview of the file types in WiX.
Note: This document assumes you have a working knowledge of the Windows Installer database format.
