He said the users are starting the server process manually.  In that
case, I believe CoCreateInstance will connect to the registered server
without going to the registry.  I admit that I have not stepped through
CoCreateInstance to see if this is the case.

If they weren't starting the process manually, then the registry would
be exactly the right answer.

Yes.
