I bought my Quicktime 4 years ago, so no app store. Haven't used it for quite sime time, but got a text file saved with the key, but can't find email with purchase confirmation. I tried all posible name combinations (my Apple ID, name and surname and vice versa, my login). Nothing fits, I get invalid registration.
Is there any kind of support that can help me? Cause I want it badly now...
The name you used probably matched the credit card info. It would be the "formal" version (Robert not Bob) of your name.
Add a Mr. to the beginning as it is also an option during purchase.
