I'm hoping to find a .NET/COM interop expert for a general installer question...

I recently came across a .NET assembly that when I call it with  regasm 
/codebase /regfile it generates a regfile that includes a registry subkey 
called Implemented Catagories with a GUID that google tells me represnts a 
generic implemented in .NET type.

But what's really special about this assembly is if I run regasm /codebase 
without the /regfile and monitor the registry, it actually implements another 
registry subkey of Implemented Catagories that has special meaning in the 
context of the system.

I was using InstallShields .NET COM = Yes functionality but the developers were 
complaining that it wasn't registered.  They would then assume it's an 
installer problem because if they run regasm on the deployed machine the 
expected functionality would stat working.

Anyone ever see anything like this and what would be jacked in .NET to cause 
it?  It almost sounds like some of the hell I used to see in the COM ATL days.  
I can do static extraction but I'm worried it could be fragile in the future if 
the details ever change.
