Try reinstalling the patch making sure to uncheck install 32 bit version.  fbs7 had the same problem over at RDNA and it appears that if you do not have a 32 bit version installed and you do not uncheck install 32 bit then it messes some files up.  He went all the way to reinstall Poser then apply the patch.
