run regasm on the assembly DLL and register the tlb!

after that run
gacutil /i on your assembly.

ps: Note that your assembly gets stuffed with many older versions if you
work like this.

If for some reason you don't want to install your interop assembly into the
GAC, you can also pass the /codebase option to regasm.exe:

regasm.exe /codebase /tlb Interop.MyLib.dll

This will register the fully-qualified path to the assembly in the registry.

The reason regasm.exe has to be used is because a CCW (COM-Callable Wrapper)
doesn't expose DllRegisterServer and DllUnregisterServer like native DLLs or
OCXs might. mscoree.dll actually acts like a shim, hosting the CLR, loading
the CCW, and marshaling calls to and from managed code.
