Windows Media Player C00D1199

Windows Media Player can't play the file. This error can occur for a variety of reasons.

Things to try:

  • Make sure the file type is supported by the Player. For a list of file types (formats) that are supported by Windows Media Player, see the "Supported file types" section.

  • If the file type is supported by the Player, make sure the codec used to compress the file is installed on your computer. Some codecs aren't supported by the Player. For more information about codecs, see Codecs: frequently asked questions.

  • Try changing the audio output device associated with the Player.

    To change the audio output device

    1. Click Organize, and then click Options.

    2. Click the Devices tab, and then double-click Speakers.

    3. In the Select the audio device box, select a different sound card or sound controller.

  • If the file type is supported by the Player, make sure you're trying to play it in a way that is supported by the Player. For example, you can't drag a DVD file with a .vob file name extension from a DVD to the Windows Media Player icon or open a .vob file by clicking Open on the File menu.

  • If you're trying to play a multipart file, use a newsreader or some other program to combine the files, and then try again.
