Upgrade Advisor will not run on my laptop. I get a message that says an unexpected error has occurred and I should reinstall Upgrade Advisor. Reinstalling does not help. I think the laptop should be a candidate for upgrade. It's a Dell Vostro 1700 a little over a year old, running the latest version of Vista. I'm concerned that if the Advisor won't run I'll have a problem with Win 7 running. Any ideas on what's going on? Thanks.
