, including the implications of uninstalling QuickTime libraries from their systems.

Media Composer uses QuickTime libraries to import and export QuickTime files and link to QuickTime files using non-Avid QuickTime codecs. ProTools uses QuickTime to playback QuickTime files, bounce to MP3, and import certain audio files. Uninstalling QuickTime completely will prevent users from performing these actions.

Avid is aware of the issues surrounding QuickTime support on Windows. We have been working on a solution and plan on releasing updates to eliminate the dependencies on QuickTime libraries. Until then, we have identified potential workarounds to allow users to continue to use Media Composer and Pro Tools with QuickTime. While we believe that these workarounds may reduce security risks, Avid does not warrant that any Avid product is invulnerable to viruses or other risks.
