Reinstall Apple Application Support

After downloading and installing Quicktime, for the first time in many years (a favorite, older, game I'm playing through needs to have Quicktime installed for movie playback) - I noticed that it installed several different components, in addition to Quicktime itself.

Being slightly irked that the installer did not mention that it needed to install the other components (had the installer asked permission/stated the pieces were critical I wouldn't care so much), I installed them, figuring they weren't really needed.

However, Apple Application Support was, and I'm wondering if there's an easy way to install it without needing to install Quicktime again - something I would rather avoid because the recent Quicktime installation unassociated a bunch of audio and movie file formats, and that's been quite annoying getting set straight again.
