You have to use REGASM instead of regsrv32 to register .NET COM components (and if it's not installed in the GAC, just the program directory, use the /codebase option), ex:

regasm MyAssembly.DLL /codebase

More than likely it will complain about it not being strongly named - you can normally just ignore that error.
