I cannot register Quicktime Pro after a clean install of Yosemite.

I've completed a successful clean install of Yosemite and reinstallation of most software. I am unable to register Quicktime 7 Pro. There is no button to click after I enter the Key code. Return and Enter do nothing. I read a suggest to press the Tab Key-- That does nothing. I've tried restoring from Time Machine, but the Key is still required. Repairing Permissions does nothing.

I would appreciate other suggestions.
