Q:
After updating to QuickTime 7.2 on Intel-based Macs, some applications may not open. This issue only occurs with applications that rely on Mac OS X's Rosetta technology for compatibility on Intel-based Macs.
 
A:
Download and install the Mac OS X 10.4.10 Combo Update.
Note: You can install the Mac OS X 10.4.10 Combo Update even if your computer is already running Mac OS X 10.4.10.

If the issue still occurs after running the Mac OS X 10.4.10 Combo Update, follow the steps below.
Note: These steps include entering commands in the Terminal application. If you are unfamiliar with Terminal and UNIX-style environments, proceed with caution.
Save your work. You will need to restart the computer at the end.
Open Terminal from /Applications/Utilities/.
Type (or cut and paste) the following command in the Terminal window:
sudo update_prebinding -root / -force
Press Return.
Enter your password when prompted.
The prebinding operation may take a few minutes. When the operation is complete, a new command line prompt will appear.
When the new command line prompt appears, quit Terminal.
Restart your computer.
