Re-installing FCP 7
Do I need to delete an existing FCP 7 before installing a recently purchased FCP 7?
My older MacBook Pro became too expensive to repair so I loaded all my files and apps from my Time Machine, but during a move I lost the box with serial # to open FCP.
Running OSX 10.7.5 on a MacBook Pro. I'm old and slow and still not yet ready for FCP X.
Also what is there a later OSX upgrade that still supports FCP 7, or should I just stay with 10.7.5?
Thanks
MacBook Pro, Mac OS X (10.7.5)
