I'm having problems using InstallAnywhere on Mac OSX 10.3.9

There is a Mac OS X bug that affects InstallAnywhere LaunchAnywheres on OS X 10.3.9 systems with the QuickTime 7.0.4 upgrade.

This appears to only affect systems running 10.3.9, and not 10.4. The current workaround is to revert to QuickTime 7.0.1, through a reinstaller available from Apple on the Support/Downloads page.
