I have a problem. I am trying to do the upgrade to Windows Vista from Windows
XP Service Pack 2. I get to the part where I have to enter my Product Key.
Ok. Thats Cool. After I click it. Nothing is happening. When I hit Control ,
Alt and Delete to bring up the task manager I see 2 setup.exe processes
running, one of which is running at 99% CPU usage. What can I do to resolve
this issue?

I am using a Dell Dimension E521 Desktop System featuring an AMD Sempron
3400+ Processor.
