just_david Posted November 13, 2014 Posted November 13, 2014 I'm trying to make a gpo to make .mkv files automatically open on all our machines in VLC player. I've got this so far [ATTACH=CONFIG]27522[/ATTACH] But it doesn't seem to be working. Am I missing something?
pete Posted November 13, 2014 Posted November 13, 2014 Your attachment isn't there (which may be because you're brand new and running into spammer prevention measures). Our file association GPO is applied at the computer level. Computer configuration > Preferences > Control Panel Settings > Folder Options > New > File Type Action: replace Extension: .mkv Associated class: VLC media file (.mkv) OK > Exit GPO, apply GPO to test OU, refresh GPOs on test computer using gpupdate /force. However: You do need VLC installed on the computer you're using to write the GPO. By default, .mkv is associated with VLC (Tested on Win7 64bit, VLC 2.1.5) if it's installed (typing assoc .mkv at the command prompt will tell you what Windows intends to use), so you may want to associated .mkv with something bizarre on the test computer (Microsoft Word, for example) and then do a group policy refresh to make sure it changes back.
just_david Posted November 13, 2014 Author Posted November 13, 2014 I see, I'm currently trying to do it via user config > Pref > CPS > folder options I'm trying your method however GP isn't giving me the option to select VLC media file in associated class, I'm going to re-install vlc and try it again and I'll let you know how it goes
just_david Posted November 13, 2014 Author Posted November 13, 2014 Okay I've managed to get vlc up on my computer and now the GPO has applied with your settings. However it still doesn't appear to be applying, I can't get it to overright MP11 assoc .mkv returns .mkv=WMP11.AssocFile.AVI Even though I've set MKV's to be associated with paint >.< although when i do try to run it it throws a paint error now. progress of sorts.
just_david Posted November 17, 2014 Author Posted November 17, 2014 I found the fix. Wierdly nither of the 2 methods worked alone, so i had to do both: user config > Pref > CPS > folder options and Computer configuration > Preferences > Control Panel Settings > Folder Options > New > File Type and point it at both the user and workstation OU
