A tool to register TypeLib or unregister TypeLib
Using RegTypeLib.exe /? to show help
Using RegTypeLib.exe /r <TypeLib file path> to register TypeLib
Using RegTypeLib.exe /u <TypeLib guid> to unregister TypeLib
Example:
        RegTypeLib.exe /r D:\a.tlb
        RegTypeLib.exe /u {bb6df56e-cace-11dc-9992-0019b93a3a84}
