rickjames Posted March 16, 2015 Posted March 16, 2015 We've had a few users today having an issue trying to access folders containing .MOV files: upon opening whichever folder that contains them, the wheel will spin for a few seconds before closing the Explorer window completely. Tested it across a few of our workstations with the same results. Any idea what might be doing this?
themightymrp Posted March 16, 2015 Posted March 16, 2015 I've seen this before. It was caused by 2 windows updates. Try uninstalling these and see if it causes the problem. They are KB2975719 AND KB2995388 If you check the event viewer you will probably find crashes related to the windows system file "mfmp4srcsnk.dll" 2
rickjames Posted March 16, 2015 Author Posted March 16, 2015 Just uninstalled both of those on mine now and it's still happening. Checked the logs and it related to that system file, anyway...
themightymrp Posted March 16, 2015 Posted March 16, 2015 If you look at the properties of that file, what version do you have? Mine is 12.0.9600.17415 I've a sneaking suspicion it may have also been updated as part of a rollup package, namely KB3013769 I've read that it could also be caused by a corrupt user profile (something to do with the windows update and how your libraries are set for viewing folders). Try creating a fresh user account on your machine then browsing to the folder of .MOV's. If it doesn't crash then you may need to just wipe a profile and let it re-create 1
rickjames Posted March 16, 2015 Author Posted March 16, 2015 Same version as you. Just uninstalled that update and my profile on various machines, still having the same issue. Eurggggggggh. Thanks so far, though.
rickjames Posted March 17, 2015 Author Posted March 17, 2015 RIGHT. Pinned this down to KB3013769 after all it seems. 1
themightymrp Posted March 17, 2015 Posted March 17, 2015 Did you just have to uninstall that one? From the KB article on that update it says that it is supposed to fix a folder view issue detailed in KB3016305. I think it's this particular part of the update which is messing with that DLL and its associated registry entries. But don't quote me on that! Thanks for the confirmation though
rickjames Posted March 17, 2015 Author Posted March 17, 2015 Yeah, reinstalled/uninstalled again just to check and that seems to be it. Approved it for removal on WSUS anyway.
rickjames Posted March 17, 2015 Author Posted March 17, 2015 Actually, ignore that entirely; removed all 3 updates from a few machines (various array of desktops) and it's still happening. ARGH.
themightymrp Posted March 18, 2015 Posted March 18, 2015 This seems to be a long running problem that is affecting MANY people: mfmp4srcsnk.dll crashing when .MOV file is selected - Microsoft Community It all seems to stem back to an issue with that .DLL file mentioned above, namely any version of it that ends with 17xxx. The older 16xxx builds don't seem to cause issues. One solution (work around really) is to download the following tool (ShellExView): ShellExView - Shell Extension Manager For Windows Run it and then search for the entry for MF MPEG4 Property Handler. If you scroll across it should be showing the name of the mfmp4srcsnk.dll Right click it and choose to Disable selected item. Close and reboot. The issue "should" be resolved, but you may not get thumbnail previews for .MOV files (and maybe .MP4 as well??) 2
rickjames Posted March 18, 2015 Author Posted March 18, 2015 Yeah I found out about ShellExView yesterday, did as you've suggested and it that appears to be OK on the surface, but what could I do to sort it across the school? Can't really walk around installing this and disabling the property handler. Many thanks on this/
Arthur Posted March 19, 2015 Posted March 19, 2015 but what could I do to sort it across the school? Deploy the following registry value via a computer GPP or startup script. Windows Registry Editor Version 5.00 ; MF MPEG4 Property Handler [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked] "{f81b1b56-7613-4ee4-bc05-1fab5de5c07e}"="" Another solution would be to deploy Media Preview if you still wanted the video thumbnails. 1
rickjames Posted March 20, 2015 Author Posted March 20, 2015 Can't seem to find that registry value?!?!
themightymrp Posted March 20, 2015 Posted March 20, 2015 It would appear that by default the 'Blocked' subkey is not there. I'm guessing you just create it (or import the above code by copying to notepad and saving as .reg). I have a subkey for 'Approved' and 'Cached'
