About War Setup
War Setup is an application for creating .msi software installation packages for Windows. It uses the free WiX toolset from Microsoft to build the MSI files, providing a graphical front-end that simplifies the process of defining installation logic, file sets, registry entries, and shortcuts. War Setup is aimed at developers who want to produce professional Windows installers without writing WiX XML directly. Requires .NET Framework 3.5.
