What is required to play. MP4 files. The default, Windows Media Player does not work.

I have Windows 7 Professional Service Pack 1.  I tried all four options of Windows when I right click and open

Make sure that your WMP is the 32-bit default (even for W7 64-bit) version. It has built more than 64-bit codecs.

Works out of the box for me.
You can always install a codec package - Klite for example.
See you soon,.

  • Windows Media Player does not support the codec used to compress the file.

    I can't do some of my videos to play it goes on to say that Windows media player does not support the codec used to compress the file. How can I fix?

    Hello

    What is the file format of the video files you are trying to play in Windows Media Player?

    Windows Media Player cannot play the file. The player might not support the file type or does not support the codec used to compress the file.

     

    You may encounter this error message for the following reasons:

    (a) the file type is supported by the drive, but the file was compressed by using a codec that is not supported by the player.

    (b) the file might have been encoded with a codec that is not supported by Windows Media Player. If this is the case, Windows Media Player cannot play the file.

    Windows media player will play only the files and videos only if it supports this type of file.

    Please see the bottom of the article that gives you information on the types of media files that supports Windows Media Player.

    http://support.Microsoft.com/kb/316992

    If the files are not supported by Windows media player, then you will need to use a few players from third party that supports this file format.

    Microsoft windows media player does not retain the previous size. is irrtating so me gift of reorganize its size every time when I open it.plz help I want stable wmp version 11, version 12 is sucks.

    Hello, Simone

    I'll assume you're on Windows 7. Windows Media Player 12 is not supported on Windows Vista or XP and as such, you will need to go back to Windows Media Player 11.

    You can check the permissions in the registry to ensure that it is able to record information.

    Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.

    Open the registry editor by clicking on start, type regedit.exe in the search box and press on enter, you may be prompted to continue.

    In the registry editor, navigate to HKEY_CURRENT_USER, Software, Microsoft, MediaPlayer, then Preferences.

    It should be an element named LastLocation_26, right-click on it and select Rename, and rename it to old LastLocation_26.

    Leave the open registry editor and open Media Player, then move it to your favorite place and close Media Player.

    In the registry editor, press F5 on your keyboard and check if LastLocation_26 has been recreated.

    If this is not the case, there is probably a permissions problem.

    If so, the location must be registered.
