Some games and apps use older InstallShield packages that refuse to complete installations.

If the installer refuses to run, grab the two zip files from here and try them with your installer.

If it runs but fails, try this out:

Stop or disable the VSS service (Volume Shadow Copy) and retry the installer.

For older versions of QuickTime, further admin folder permissions may be required.
