If you have an upgrade key, it can't be used to install by booting the DVD.
Just don't put in any key and select the proper version from the next menu.
When installation completes and you can load Vista, reinsert the DVD while
fully booted and do an in-place upgrade, this time using your product key.
Basically, you will need to install twice, then activate the new
installation by phone (your key will be reported as being in use, and you
will not be able to do the automated activation).
