I am having the exact same problem as you. I have found some instruction in the read me file at the following McAfee link.http://www.mcafee.com/apps/downloads/security_updates/superdat.asp?region=us&seg ment=enterprise. The part you are looking for is titled MODIFYINGTHE SUPERDAT PACKAGE TO WORK WITH AUTOUPGRADE. However, I can't get this to work either. I still get the same error you are getting. See if you have any luck. Let me know if your successful.
what corporate supplied repository files are you getting?
I've done this before by setting up a mirror task on any machine that has virusscan on it. Then copy all these files to your share (get them to provide these files). (watch permissions etc) and use this.
