I have quicktime 7 installed and when I use my registration # to register Pro nothing happens
Is the purchased key for the correct platform? (I.e., Windows keys don't work on Macs and vice versa.) Is the "Registered To" entry entered exactly as the name under which it was purchased? (I.e., salutaions and suffixes are significant if used in the purchaser's account name.) Was the key entgered or copied exactly as contained in the confirmation email?
What does "noting happens" mean to you? Did the QT icon change (have Pro superimposed on it), do the "grayed out" options become available if you load a file, do you have access to the "Properties" window, etc? (I.e., in some cases users have avctivated their Pro key but did not recognize this fact for one reason or another.)
