"Incompatible Version of the RPC Stub" Error Message with the InstallShield Program:
http://support.microsoft.com?kbid=321915
Check Control Panel> Add\Remove Programs for Gator, Webhancer, Web 3000, Delfin, or Promulgate, and uninstall them. They may still be on the machine and not in Add\Remove. You will find them by installing and running Ad-Aware 6 free edition. Remove whatever it finds.

If you still have the problem, install DCOM98.
