For the life of me I can't find on 2 systems, where the QuickTime Control Panel is. On my Blackbook and my Pro, System Prefs don't show any QuickTime at all. I have 2 players (QT7 as well), neither have anywhere I can enter a QT Pro serial number.
So what do I do? I'm running 10.6.4 on both machines from the same install DVD, then updated through Software Update.
G5 1.8, Blackbook 2.0, Mac Pro 2.8 (8c), iMac 17 2.0, Touch2, Shuffle2, iPod40, Mac OS X (10.6.4), iPhone? Heck I'm still giggly about MultiFinder!
