Every time I update Quicktime on both Vista and XP, I lose file associations I made for VLC (my preferred player). I only keep QT around for the odd browser video, and would prefer to keep it without it surprising me every couple months by stealing file associations.

  • This is what I hate the most about Quicktime also. Jul 16, 2009 at 23:58
  • Agreed. Also with regards to the answer about advanced setup, I've checked the appropriate checkbox every single time I install Quicktime and without fail it steals the associations it wants from. So incredibly annoying. Jan 3, 2011 at 15:17

Buried in the advanced setup there is a checkbox to keep it from checking and reclaiming. Wish I could remember where though... I stopped using QuickTime a while back in an effort to simplify the media players that continually were sprouting on my PC... MediaPlayerClassic Home Cinema handles everything I need it to and then some.


If I remember correctly, QuickTime has some stuff in its settings about file associations, or something that takes you to a tool to manage them.


I would highly suggest using Quicktime Alternative instead of the full blown Quicktime from Apple. It has plugins for all the major browsers and allows you to play Quicktime files in any video player. I have never had a problem with file associations using this software.

  • Does it allow you to watch HD trailers on apple.com?
