Invisible MP3 files in Windows Media Player

After a registry cleanup, I ended up in a strange situation. Windows Media Player 11 will play MP3 very well, if I double click on an MP3 file in Windows Explorer to the media player will start and play the file.

If however in Media Player, I open a file I don't see any MP3 file, if the file type is defined for media files (all types). In the drop-down menu, I don't see a type of MP3 file. If I select all the MP3s files are displayed and can be read.

Where and how can I reset the media player will identify the types of media?

Thanks in advance!

OK, I found the problem!

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer\Extensions the following is missing:

In the Descriptions:

1 file REG_SZ Audio (*.wav; *.snd; *.au; *.aif; *.aifc; *.aiff; *.wma; *.mp3)

In MUIDescriptions:

1 REG_EXPAND_SZ @%SystemRoot%\system32\unregmp2.exe,-9995

In Types:

1 REG_SZ *.wav; *.snd; *.au; *.AIF; *.aifc; *.AIFF; *.WMA; *.MP3

I found these comparing entries to those for the 32-bit version of media player. After that I added these entries media player launched recognizing MP3s again!

    Original title: Media player upgrade was worse than basic
    I recently updated my Player multimedia media Player 11 and now it won't play movies from AVI file that I used to be able to play easily on the outdated version. Why is this?

    Hello

    Do you have an error message when you try to play with Media Player AVI files?

    When you try to play a file that uses a codec that is not installed on your computer, Windows Media Player attempts to download the codec from a Microsoft server. If the
    Codec is available, the Windows Media Player installed on your computer, and then bed file. However, if the codec is not available on the server (for example, because)
    the codec not created by Microsoft), Windows Media Player displays a message that your computer is missing a codec.

    In some cases, the file you want to play uses a codec that is not available or compatible with Windows Media Player. When this happens, you may be unable to use Windows Media Player to play this particular .avi file.

  • Play AIFF files in windows media player

    Hello

    I'm reading some AIFF files in windows media player. I get the error message "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."

    As WMP supports AIFF files I guess it's a problem with the codec.

    Is there a solution out there that I can play the files?

    Cheers, Matt.

    Where are the files? Are you sure that they are in the AIFF format?

    You can try to install FFDShow . If this does not help, please open some of the files in GSpot , this program will signal the audio codec used in the file. Then, you can report this codec here.
