Windows Media Player is not installed properly and must be reinstalled

    Question

  • Hello Rooms,

    I have Window 7 Ultimate 32 bit and I installed Window Player version 11 and 12.

    When I run the Window Media Player, I received an error of "Window Media Player is not installed properly and must be reinstalled."

    Then, I run the Window Media Player as Administratior Window and I still received the same error.

    I already tried to turn Window Media Player on and off but it did not help.

    Can anyone help please?

    Thanks,
    Edwin

  • Hi,

     

    I would like to suggest you uninstall Windows Media Player (WMP) 11 and confirm that can WMP 12 work now?

     

    If WMP 12 still cannot work normally, I would like to suggest you disable and re-enable it in Windows Features to reset the WMP components.

     

     

    Does it work?

  • Installing WMP 11 on Windows 7 is not supported. You can use System Restore to roll back to a state before you installed WMP 11. If that doesn't help, then you will probably have to do a full Windows reinstall to fix this.

  • I don't believe this.  Both are Microsoft products. Should Microsoft prodive a work around solution?

  • I thought that you were blocked from installing Windows Media Player 11?  The Windows Media Player 11 team, which was extant during the Windows Vista product cycle, was not actively working on Windows Media Player 11 during Windows 7 (since they were working on Windows 7's player) and thus WMP11 would not be expected to be compatible with Windows 7.  And isn't.

    The solution is Not To Do That.  To install WMP11 on Windows 7 requires stomping on many files that are NOT covered by the Turn Windows Features On or Off player install option that Windows 7 has.  You can potentially use that (TWFOO) in conjunction with "sfc /scannow" (admin tool) to maybe get things limping.  But generally you've borked your system: the error you're getting is very specifically because you hacked your system.

    Was there some way in which you thought this was supported?  If you didn't get a block or error, I'd be very interested in knowing about that.

    Just want to add that the only supported way to get WMP 11 on Windows 7 is by installing it in XP Mode .

  • ^-- Note that while I generally fixed doing a "regsvr32 wmp.dll" on WMP, that that's redundant with the use of a Windows Features reinstall and shouldn't be recommended.  RGS was deprecated internally for WMP here back in Vista, and manual DLL registration (calling the RGS) can cause issues.  The RGS is *not* kept in sync with the new MAN.  To use the new MAN, use Windows Features only.  The RGS should *generally* match the MAN, but that's not an area where any investment whatsoever was made.

  • Hello -

    I had this problem with WMP 12 running on Windowws 7 Pro (x86).  What finally worked was this:

    Remove and reinstall WMP 12 using the add/remove features

    Run Regedit

    Navigate to HKLM\SOFTWARE\Microsoft\MediaPlayer\Setup

    delete the "Installed Versions" subkey

    Open an Administrative Command Prompt

    Change to C:\Windows\System32

    run: UNREGMP2.EXE /UPDATEWMPVERSION

    WMP opened fine for me after this.

    Good Luck!

  • I run Windows XP SP3 due to a DOS business program that will not work under Windows 7 Professional 64 bit (which I also have on another partition).

    I get the error message: Windows Media Player is not installed properly and must be reinstalled. I have uninstalled WMP 11, which rolled it back to WMP 9. Then I receive the same error message. I also tried to use MS Fixit, but received an error message for every option. What is going on here? I have all available Windows Updates. I do not want to reinstall my OS. Please help - thanks.

  • wildbill562: this forum is for Windows 7, so I suggest that you repost in the XP Music and Sound forum:
