FIX: Files and registry keys for the installation path incorrectly disappear when you run an .msi file for a Setup project that was upgraded from Visual Studio 2008 to Visual Studio 2010 SP1

To resolve this issue, apply this hotfix, and then set the new BackwardCompatibleIDGeneration property to True before you build the project. 

This hotfix introduces the BackwardCompatibleIDGeneration property. By default, this property is set to False. Before you build the Setup project in Visual Studio 2010 SP1, you have to explicitly set the BackwardCompatibleIDGeneration property to True.
