I'd hazard a guess that the file will need to be resigned. Update KB978601
changes the way in which cabinet and executable files are signed; I'm not expert
in this area, but from my interpretation of it this change will invalidate
previously good signatures under certain circumstances.

You might get better advice in microsoft.public.security.crypto.
