[Windows Fix] “Media Foundation Protected Pipeline EXE has Stopped Working” Error Message

This problem occurs when ”Media Foundation Protected Pipeline EXE has stopped working” error message is displayed by Windows whenever you try to transfer video files from your PC/laptop to your mobile device. Sometimes this error message is also shown when you are playing a video or song online in a web browser or offline using Windows Media Player. The video file format can be any popular format such as MKV, WMV, FLV, AVI, MP4, MPEG, etc.

This problem can occur due to following possible reasons:

• The “mfpmp.exe“ or ”mf.dll” files present in ”C:\Windows\System32“ folder are corrupt.
• A plug-in installed in Windows Media Player is incompatible and causing this issue.

To Fix this issue, you can try following solutions:

SOLUTION 1: Disable Plug-ins in Windows Media Player

2. Now press ALT key to show menu bar and select Tools -> Options.

3. Go to ”Plug-ins” tab and check following plug-ins:

• Video DSP
• Audio DSP
• Other DSP

Now try to copy videos from your computer to your mobile or try to play the problematic video and it should work fine.

SOLUTION 2: Rename or Delete MFPMP.EXE and MF.DLL Files
