As per Vista's Help & Support section:
"You cannot use Windows on more computers than the Microsoft Software
License Terms allow. Usually the license terms allow one copy of Windows to
be used on each computer. To use the same copy of Windows on another
computer, you must uninstall Windows on the first computer before installing
it on the second one. You will need to activate Windows again as part of
installing it on the second computer. During installation, enter the product
key that came with your copy of Windows. If automatic activation fails,
follow the screens that walk you through activating Windows by phone. You
will have 30 days to activate your copy of Windows."
So the phone option is the one you want. I trust that you wiped the hard
drive clean on the machine you sold. If you sold it with Vista intact, then
you sold your Vista along with it, and you might as well send the DVD to the
buyer as his/her backup.
