There is no danger in redoing a registration that has already been
done.  All it does is add some registry keys.  Might as well just do it
every time.  Add "/s" if you don't want to see the dialog box.

Alternatively, assuming you are running a 64-bit Python, you can just
call the registration entry point directly:
    import ctypes
    dll = ctypes.OleDLL('myComServer.dll')
    dll.DllRegisterServer()

That's exactly what Regsvr32 does.  It is not a highly sophisticated
application.
