Consider the following scenario:
In this scenario, the files and registry keys for the installation path disappear unexpectedly.
This problem occurs because a different hashing algorithm is used to create the GUIDs in Visual Studio 2010. When you install the MSI file that is created from the Visual Studio 2010 Setup project, the MSI file determines that the GUID has changed and removes the files and registry keys for the installation path based on the sequence of the project.
To resolve this problem, apply this hotfix. This hotfix introduces the BackwardCompatibleIDGeneration property. By default, this property is set to False. Before you build the Setup project in Visual Studio 2010, you have to explicitly set the BackwardCompatibleIDGeneration property to True to enable the hotfix.
