Welcome to the Apple Support Communities
QuickTime only appears on System Preferences if you are running Mac OS X Leopard, and you have OS X Mountain Lion.
In Mac OS X Snow Leopard and newer, QuickTime Player 7 isn't included, so you have to install it before getting QuickTime 7 Pro > http://support.apple.com/kb/ht3678
After installing QuickTime Player 7, you have to activate it in order to get QuickTime 7 Pro. In that link, follow the steps under "Information for QuickTime 7 Pro users"
