Windows Media Player 12 Error C00D11B1 Frustration RRS feed

  • Question

  • I just upgraded to Windows 7, and now any .wma file that has DRM will not play.. (this is on 2 different machines)

    I get this msg first, when trying to open the file in WMP 12


    After I open Zune software, and play the file as instructed I get this error when trying to open the file in WMP 12


    I have re-installed DRM, Re-installed WMP 12, gone over many document on the net to fix similar sounding problems but not one has worked, spending hours trying to fix this...

    These files play perfectly in Zoom Player, Zune, Nereo Showtime....

    Is there anything I can do here? Or should I just give up and move to a DRM Free music service..???

  • Hi,

    I would like to know where you get the DRM protected .wma files.

    Did you try the DRM reset tool as below?

    You can also try the following methods:

    Method 1. register DLL files:

    1. Click the Start button, type CMD in the Start Search box.
    2. Right click on CMD and choose Run as administrator.
    3. Type the following commands and press Enter at the end of each line:

    Regsvr32 MSMPEG2ADEC.dll

    Regsvr32 MSMPEG2VDEC.dll


    Method 2:


    1, Click the Start button, type Regedit in the Start Search box and press Enter.

    2, Navigate to the following key:


    3. Right click on Audio and choose New -> DWORD value

    4. Name it as DisableProtectedAudioDG, change the value from 1 to 0.


    NOTE: Please backup registry before making any change.


    Method 3: Update BIOS and device drivers to latest version.

    Please also check if the following article works:

    When you try to play music that you downloaded from the Zune Marketplace, you receive an error message: “C00D11B1”:

    Hope it helps!

  • Hello Vivian,
      Thank you for you suggestions..  I get the DRM music through my Zune subscription, and I hate the Zune PC software....

    I tried all the suggestions, and then I found the MS Fixit thingy, and that actually worked, BUT it left me with a different problem...

    Now when I play like 12-15 music files, I get an error msg "You must restart the machine to continue content processing." in the caption of this msg box it says "Windows Media Revocation and Renewal".....

    At this point, I again cannot play any protected .wma files until I reboot my machine...

    This is sooooo crazy....

    This issue can be caused by third party program. Please test it in Clean Boot mode.

  • Hi,

    I get the same error message on my PC, but I am trying to play a Digital Copy of a movie.

    I contacted the studio, and they let me redownload the files, and the problem persists.

    I tried all the steps here - - and nothing works.  What can I do?

  • Methode 2 above may solve the problem for Napster files that can't be played in WMP.
