Video type wallpaper won't play

[76561198064765786]

Getting an error every time I try to load a video type wallpaper. I have a dual monitor setup and scene type wallpapers work fine.

C:\WINDOWS\System32\mfmp4srcsnk.dll either not meant to run on windows or getting an error

Error status 0xc000012f

Any help would be appreciated!

Your Windows files are corrupted and they must be fixed for Wallpaper Engine to work right.

Try this: https://www.lifewire.com/how-to-use-sfc-scannow-to-repair-windows-system-files-2626161

If that doesn't work then delete mfmp4srcsnk.dll first and try it again. Delete it from System32 and SysWOW64 in the Windows folder.

So I deleted mfmp4srcsnk.dll from both System32 and SysWOW64 and ran the scan, but this came up after the scan.


Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

So it seems to have fixed the files, (I'm assuming) but now when I try to load a video type wallpaper instead of popping up with the previous error with mfmp4srcsnk.dll, no error pops up and the video wallpaper still refuses to load. Gonna see if restarting my computer solves the issue.

If that also doesn't end up working then both the file and the local backup Windows had were corrupted/missing. Short of reinstalling Windows I do not know how you could fix your PC easily.

However maybe this alternate video system works even without those Windows files that you are missing: http://steamcommunity.com/app/431960/discussions/2/1484358860951576217/
