Firstly, this post has nothing to do with iTunes on the Macbook.
[Moderator note: The duplicate thread started by plisk10, with the mislelading title "Macbook Itunes", has now been merged into this thread.]
Anyway, I'll try and help. I don't actually have this app, but once you have launched it, click "Final Cut Studio", in the top right, and in the dropdown menu, there should be "About Final Cut Studio". Click it, and you should be able to find it.
