Windows Media Player Won't Play .mp4 when it once did and other players will

    Question

  • Hi All,

     

    I have .mp4 files which I received off a mate. It was working fine on Windows Media Player (I have WMP12 and windows 7 home premium) and I had it on my external hard drive. I was half way through watching it (Was watching it through my PS3 using media player as a media library) . Then my house mate disconnected the hard drive while I was away. I have then come back and every .mp4 file within that folder will not play on WMP (They worked before and still work on other players). Whenever I try playing it I get "http://windows.microsoft.com/en-au/windows7/c00d11b" . I have deleted the files (Thinking they were now corrupt) and put them in the same folder and still won't play. Anyone have any help with this problem? I really don't want to change players but might have to.

     

    Cheers, Nic

  • Type msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic in Start Search and hit Enter to open the troubleshooting wizard which will help you reset WMP to default settings.

    You could also use the Fix WMP Utility from thewindowsclub, which re-registers all concerned dll’s required for the smooth functioning of Windows Media Player.

    Or,You may reset WMP12 AS SUGGESTED BY Lany Zhang.
