PC came with Vista installed (have disk). 2 months ago upgraded to Windows 7 by buying W7 Upgrade disk. Following recent hard drive failure I reinstalled W7 using W7 upgrade disk only. Now online activation system says they won't accept W7 activation code because I didn't reinstall Vista first. They say the W7 disk is for upgrading only. Can they make me reinstall my OS again, Vista first, then W7 upgrade? Or will they allow me to activate W7 as is? I have valid disks, licences and codes for both Vista and W7 and am using on only 1 PC. Surely they can tell that from their records of my PC's hardware configuration. Grateful for suggestions please.
Normally for an upgrade, the installation will ask you to insert the install disk of the older OS before starting an upgrade installation. Failing this, though, I would have thought they would accept you merely reading them the Vista product key?
