Fix: Windows Media Player is not installed properly and must be reinstalled.

You might have faced the problem, when you try to run Windows Media Player. An error dialog box appears “Windows Media Player is not installed properly and must be reinstalled.”

Literally it happens due to mismatch version of some core Windows Media Player files. Following reasons may cause the problem like this-

  • Windows Updates might have failed to installed Windows Media Player updates.
  • You might have patched Windows Media Player files like wmplayer.exe, wmp.dll and so on.

The error messages may differ, but primarily it state

Windows Media Player is not installed properly and must be reinstalled. Do you want to reinstall from Microsoft website?

    Step 1 .Delete Window Media Player Folder in (C: Program File x86) if u can’t delete it (before delete u can copy and back up if not sure) then use {iobit unlocker} to Unlock and Delete it.
    Step 2 . Copy Window Media Player Folder in ( C: Program File) to (C: Program File x86)
    It worked for me. I am happy now :D Try it if u think it could help for u (Friend).

    Tried to start wmsetup.exe and a message that said “there is a newer version already installed, can’t use an earlier version to setup the program.

  • Joe

  • Briony

    Wow, that Christian person, their method actually worked. :|

    I’m kind of surprised to be honest. I’ve been looking for solutions to this problem for about half an hour, and I was seriously losing hope. There was no way I’d do a System Restore, so I figured it was Goodbye WMP. So, thankyou kind fellow, lol. Very much appreciated.

    Please Help!

  • christian

    i found a solution…

    this is for windows 7…
    click start and locate windows media player in there…dont click, instead right click on it and properties…click the “shortcut” tab…check in the “target”, is it says this:(“%ProgramFiles*86%Windows Media Playerwmplayer.exe”) or something like that….delete “*86″…and the delete the rest after the qoutations…i forgot what it says the last time…but im pretty sure its like “prefetch=1″ or something…delete that…
    and still in shortcut tab…check in the “startin” delete *86 too…and try opening the media player again…see if it works

    • Emily

      That WORKED! Thank you because nothing else worked and I didn’t want to do a system restore. You are awesome!!!

    • use_vlc

    • mememe

      OMG – I JUST JIZZED MY PANTS! I have been trying to get my WMP to work ever since I first installed windows 7 when it first came out. This finally fixed it.

  • Tim

    1. First, please delte the DRM folder on your computer. Depending on your OS, it can be found in different locations:
    * Windows 2000 and XP: C:\Documents and Settings\All Users\DRM
    * Windows 98: C:\Windows\All Users\DRM
    * Windows Millennium Edition: C:\Windows\DRM
    If you cannot find the folder, it may be ‘hidden’. Please use the following steps to view hidden files and folders.
    * In Windows Explorer go to Tools > Folder Options > View
    * Under ‘Hidden files and folders’ heading, make the following changes:
    o Select ‘Show Hidden Files and Folders’
    o Un-check ‘Hide Protected Operating System Files’
    * Click the button ‘Apply to All Folders’. This will ensure the changes affect all folders on the system.

  • Kate

    Sorry, I run Windows XP. On Windows XP the resolution is:

    Start -> Run -> Type in: %SystemRoot%\inf\unregmp2.exe /UpdateWMP -> OK

    Besides, I found a solution to my problem:

    1. Uninstall Windows Media Player 11 and Restart.
    2. Uninstall Windows Media Format 11 Runtime and Restart.
    3. Reset existing DRM License Key by deleting the contents (hidden) of DRM Folder:

    C:\Documents and Settings\All Users\DRM\

    4. Install Windows Media Player 11.
    5. Go to Microsoft secure server for WMP DRM individualization.


    • Bas

      Thanks that worked for me too.

    • Christopher Robin

      Yay, your Start/Run solution worked where others failed. Thanks! :-)

  • Kate

    1. I receive this message:

    “Windows Media Player is not installed properly. Reinstall the Player.”

    when WMP11 opens DRM protected videos as well as when trying to start WMP DRM individualization process at Microsoft secure server:

    2. The problem appeared after System restore to a previous restore point, made a day earlier, when WMP11 played DRM protected videos without problems.

    3. The above solution did not work as such a file “unregmp2.exe” does not exist on my C:\ drive.

    4. Other solutions ?

      unregmp2.exe is located in C:\Windows\System32 folder. So move to that folder and execute the given command. Like:
      C:\Windows\System32>unregmp2.exe /UPDATEWMP

  • Alicia

    How do I get to the C:\Windows\System32 ? I tried several times under “run” and nothing happens.


    Got a somewhat different problem … media player somehow got uninstalled from Win 7 64 and Microsoft insists there is no download available for my system to reinstall it … and I can’t find anywhere on the Win 7 install disc to install, reinstall or repair features (XP was much more user friendly in that regard) … the only option seems to be to reinstall the whole program. (Which can’t be right, so I’m probably missing something.)

    Have tried to install older versions of MP, but get the dread “newer version” error and the unreg code doesn’t fix it … do I really have to go into the registry and weed every single reference to media player out by hand to install, say, Media Player 11, or is there a Windows 12 download (apparently I need version 7600.16415 or newer) somewhere on the black market.

    I mean, really, OK, Microsoft is stupid, dump and as covered with disease carrying flies as a pile of rocks covered with steer manure always and forever, but even for the Redmond Rapists not providing a download to repair or reinstall a key component of their latest, so-called greatest operating system is beyond the pale.

    Not that anyone in their right mind would voluntarily use Media Player for anything, but, sadly, the issue of voluntarily doesn’t enter into the equation when third-party vendors like Napster or Rhapsody demand you have it on your hard drive to access various of their functions.

    Thanks for the help.

  • Manu Bhalla

    I dont get how to execute the command… where do i type the command and how do i execute it??

  • Glenn

    I’ve tried this several times and it does not work. It comes back and says “not an internal or external recognized command” or something like that. Any other ideas?

    • Author

      You must run Command Prompt (cmd.exe) as Administrator and execute the command from C:\Windows\System32

  • Mitch

    Sadly it didn’t work for me, after trying several times, no dice

  • Monica

    I can’t believe that such problem can’t be fixed!
    Seems so simple, but no one can say what’s going on, all the steps done and nothing, bah.
    Well perhaps someday…

  • hun

    No go on my Win 7 either… I have re-nstalled this version at least 7 times:-) and still it is not what i was expeting.. I want my computer back!! I know the DLL file problem with the Windows Media Player but Ihave no privalage to fix it:-(

  • Khim

    Thank it helped me to fix this issue in Windows Vista.

  • Monica Santos

    Thanks for the prompt answer but I did the steps you’ve described many (several times) and well those steps doesn’t help as I use a notebook I need to enhance my sound, and reinstall eveything right now is not an option I am so tired of that…
    Thank you so much again.



  • Monica Santos

    Greetings thanks for all the useful tools and tips, I made the download of Fix WMP and run the program, but my main problem is:

    01 – When I start to listening to the music this info does not appear at my Live Messenger no matter what I try, I cannot fix such problem;
    02 – Since WMP 11 I use DFX Sound Enhancer and SCII Decoder v. 1.4.2 (what gives me the surround sound);

    Is possible to find a way to fix my problem?

    Thanks in advance.



    • Author

      To show current playing track as the Live messenger status, you need to check two settings-
      1. Goto Windows Media Player Options (Tools menu >> Options), on Plug-ins tab chick on Background under Category and then select Windows Media Player Music Plugin. Click on Ok or Apply to commit changes. It may require to restart your Windows Media Player.
      2. Sign-in Live Messenger, click on Status Split button and choose Show what I’m listening to
      FYI: DFX Sound Enhancer gives your sorround sound, SCII Decoder is the plugin, that might be installed by some 3rd party applications.
