This should give you a clue. The PC must have been on a network at some time or other? Is it still networked now? If not, there may some links that still point to the network. Make sure there is no virtual network drive attached.
Post back - meanwhile I will do some searching.

Hi: I just saw CrankyFluff's advice to try
http://support.microsoft.com/kbl/290301 which is Mircosoft Install clean up utility and gave it a try. It deleted Ad-Aware 2007 from my computer and I was finally able to install Ad-Aware 2008! If I was ever on a network, I did not know about it. There have been others on my computer, so who knows. Thank you for being there, I appreciate it.
