You also have an answer in your other post, but setting the Register property to
vsdraCOM for the assembly is the way to do this. This causes VS to run regasm
during the build and extract the required registry settings into the constructed
MSI file. If you nail down your CLSID in the class attributes, you can install
the MSI file on some other system and check that HKCR\{CLSID} refers to your
assembly name, sn, class name, version etc.
