Apple sent the following article to me; my computer is not listed, but when I attempt to use BootCamp to install Windows Vista, I am only give the choice of installing Windows 7 driver, and installing Windows 7. I tried installing Viata, but my serial number was rejected. This is a factory purchased disk, and was installed on my iMac before I installed Lion and then Mountain Lion.
