There's a 'Known Issue', a patch that's needed for FC6. 'Pro App Package'. In any event, I resorted to the Apple Software Update. Understandably, there were 'other' more recent updates, newer than my archived patches.

This was very helpful, (below), in my situation. Following a customized install/format of OS 10.4, and after installing the 10.4.11 Apple OS Combo, then the security patch, I installed Final Cut Studio 2. I'm not absolutely sure there's a sequence required for the FC updates. I started with all the 'Pro Ap' updates first, earlier to later, then installed the remaining updates. All is well ....
