Visual Studio 2010 Setup MSI how to add content file's path to registry

Is there a simple way to add one or more content files path's to the registry under the manufacturers's program file path for the current user? I was able to do this for the executable file but not for any of the added content files.

I had to put the registry entries in the registry editor. I also had to use the using statement and place .net code to add registries within the using statement else it lost context.
