Hi relayer77, you should first have a look on what is now installed or not.
Can you see under VirusScan extensions if any report extension is installed?
You should also have a look again at c:\Program Files\McAfee\ePolicy Orchestrator\Server\Extensions\installed\ and see if you have any VIRUSCANREPORTS folder (if it exists then look at folders inside it)
With SQL Management Studio or SQL Management Studio Express have a look at the OrionExtensions table (dbo.OrionExtensions) if you have an entry with VIRUSSCANREPORTS extension and its version (if exists)

Problem solved. It turned out that we had to delete the Viruscan Enterprise queries that existed under menu | queries | Shared Groups | Viruscan Enterprise. For some some reason a (probably corrupt) query was blocking the install. At this point, i don't think any of the other troubleshooting steps we took were relevant or helpful. I hope this saves someone else some time. I troubleshot this for about 15 hours, and now I'm ready for a nap.
BTW, yesterday we, too, checked the db table 'orionextensions' and did verify that the requisite entry for viruscanreports was missing. Until we figured out the queries - related solution above, we were trying to figure out if there is a way to take that entry from a different db table and import it. Ever tried that successfully?
Thanks again for the reply!
