    WMP11 FourCC 0x50 Codec Missing

    I have spent hours researching this on the web but have yet to find the final solution / codec source.

    Someone...please help.

    I have installed iTunes and I can play my file just fine...but I want to fix the problem with WMP anyway.



    I ran GSpot270 and I cannot really interpret the results any more than the file plays / test-out just fine.

    So...GSpot270 says everything is good but WMP won't play the file and the codec Vista says is missing is nowhere to be found on the internet (so far anyway) as a stand-alone download (codec packages are available...this is the extent of HP support's support...but they did nothing, so I uninstalled them for fear of the corruption I have read about).

    Any advice greatly appreciated.

    What file are you trying to play..mp3, ogg, flac? Is it a video file..sounds like it..

    It is an audio file...a plain old mp3. The funny thing is all other mp3 files play fine...so do videos.

    Why is it that WMP thinks it is an mp1...or at least needs a MP1 codec to play it?

    Here is another thing. You know those ghosted-out words that show the loading and processing process of files when you open them in WMP (in the lower left corner). Well, right before I get the message saying the codec is missing, guess what appears in that corner..."codec acquired".

    Any help will be appreciated.

    Thanks.

    OK, so all other mp3s play fine except this one...have you tried playing that particular file in a decent player like foobar or winamp(wmp sux big time)? Could be the mp3 is knackd.
    I never use WMP..no plugins, cant get 7.1 or 5.1 surround..simply Shiiiite IMO, LOL>

    Yes...works fine with iTunes. I honestly don't know why I am spending so much time on this...I just want to fix the problem.

    I found this fix on another thread, posted by brady lee, but it did not work for me.

    On Vista-
    Go to Computer
    C:
    Windows
    System32
    Look for a file called l3codecp.acm (you'll probably find l3codeca.acm which is why you're having the error)
    If you find l3codeca.acm continue on........
    Close out of that
    Go to start
    Run
    Type regedit
    Click the arrow next to Hkey_Local_machine
    Then click the arrow next to Software
    Arrow next to Microsoft
    Arrow next to Windows NT
    Arrow next to Current Version
    Then highlight or click once on the name Drivers32
    On the list to the right it will say msacm.l3acm then to the right of that under "Data" it should read C:\Windows\System32\l3codecp.acm(will probably say l3codeca.acm)
    If it reads l3codeca.acm you need to right click on msacm.l3acm and click MODIFY

    Once in there, leave the data that's already there, just find the spot where it says
    l3codeca.acm and replace it with l3codecp.acm- (you're only changing one letter the A after codec to a P) click ok restart your computer and it WILL work!! It sounds complicated but if you follow everything I say, it will work like a charm and you won't have the problem again. If you know of anyone else having the same problem direct them to this and have them run through it.


    The funny thing is, at the final step the data for the entry "...l3codecp.acm" was suspiciously empty. I will try to add the same data file and see what happens.

    Hmm..OK another thought. Try to convert it to WMA...native windows media player file. See if that does it. There are plenty of free converters out there.
    Also...found this which seems similar to the solution you quoted, but simpler..

    Excellent. I will try that.

    Well my improvised fix did nothing. Would you recommend I go back into the registry and undo my changes?

    You backed up your registry before working on it I hope.
    For my missing codecs I used the cole2k media pack and it solved all my missing codecs including FLAC everything plays fine now.
