I've retrieved my key from my Apple account countless times in the past when I've reformatted my PC. Now when I go to order history, it's nowhere to be found. Any ideas?
Apple has changed their Site many times since QuickTime Player Pro 7 was released in April of 2005 and "Downloadable Software History" links have been dead for a while.
You could search through your emails for the original order from Apple or call them on the phone?
