Received the following LINK : fatal error LNK1158: cannot run "cvtres.exe".

Working on a VB6 project and suddenly am getting this when trying to create an installation package, or File>Make. Not sure what happened and doesn't seem to be anything new that was done on the Windows XP VM I'm running the development software on. A search for cvtres.exe resulted in finding 2 copies, both located in then Microsoft.NET\Framework directories under different versions.
