if you used an upgrade disk and put in your activation key after you did
a clean install, you will get the activation key is in use message.
Doing a clean install using the undocumented work around by installing
without using a key and not activating, then running setup from within
vista, reinstalling vista normally , should work for you. The same
thing happened to me with an ultimate upgrade. Do a google search for
more detailed instructions on the work around for a clean install of vista.
