QuickTime

Some older games require QuickTime to run, similar to how many others require DirectX. Sometimes, QuickTime will be bundled with the game installation, but fairly frequently it needs to be installed separately. First and foremost, check the folders on the game disc, as any extra software the game requires will frequently be found there.

As QuickTime was designed for Windows XP and Vista, it is likely to run into problems with other operating systems. Running in compatibility mode is highly recommended if you try installing it on a newer version of Windows.

Several versions of QuickTime can be found at the Apple Support website. Official support for the program ended in 2009, however, so asking Apple for help is unlikely to get you any answers.
