Thank you for the reply. I am using Vista Business and have had all kinds of issues with this program from problems with itunes to Lime-wire. I believe it may have to do with Vista Business edition missing the media handlers.

Here is what I had to do to get Lime-wire to install correctly and work. I too was thinking virus, I use AT&T's security suite and ran a full scan and the system was clean. Next I ran a spyware scan and found grokster and Lime-wire spyware, removed those removed all entires in the registry that dealt with Lime-wire restarted the system, disabled the security suite and ran the install. Success
