Help Upgrading To QuickTime Pro

I would like to purchase the upgrade to QuickTime 7 Pro. It says the following before upgrading:

"Please note:

Your QuickTime 7 Pro registration code only works with QuickTime 7. Be sure you have downloaded and installed QuickTime Player 7 before you enter your QuickTime 7 Pro registration code."

But my current version of QuickTime is 10.2. Do I actually have to install an earlier version of QT, (Ver. 7) before I can install QuickTime 7 Pro? Or is there a QuickTime 10 Pro and I just don't see it?

Thxs for any help.
