Hi Alex, I created a wix file using the Major upgrade wix file sample described by you. It works great. The wix file I created is for a Visual studio package application. Alex Shevchuk : From MSI to WiX

WiX Tutorial The Windows Installer XML (WiX) is a toolset that builds Windows installation packages from XML source code. The toolset provides both a command line environment that developers may either integrate into their oldstyle Makefile build processes or use the newer MSBuild technology from inside integrated development environments like Microsoft's Visual Studio or SharpDevelop to build their MSI and MSM setup packages. WiX is an open source project, originally developed by Microsoft and maintained by Rob Mensching. You can download the latest binary and source code releases.
