I downloaded Windows 7 Upgrade Advisor twice, using ‘Remove Programs’ in between. I get the initial screen each time, click on ‘Start check’ and absolutely nothing happens. I left my PC on overnight and only the initial screen is there. I am running on a Dell Vostro 1500 with Windows XP SP3. .NET 2.0 is installed, along with 1.0 and 3.5.
