So I have a 2008 iMac with Quicktime Pro installed. I never bought a serial or anything, it just came like that. When I click Registration it does not show me a serial or anything, but states that it is indeed the Pro version. My 2011 Macbook Pro only came with the new Quicktime which I don't particularly like and I want to use Quicktime Pro 7 on that computer. But since I don't have a serial is there anyway I can do this? I don't understand how I have Quicktime Pro without a serial.
