Resolving "Unsupported Operating System" Error in Windows Media Player 11

Fresh install of your slipstreamed Service Pack 3 media and missing Windows Media Player 11? Microsoft has yet to update the WMP11 download to support clean installs for Media Center with Service Pack 3, but here’s a fix that should work on any XP installation where you encounter the problem:

  1. Download Windows Media Player 11
  2. Using WinRAR, 7zip or any other archiving app that can support it, extract wmp11-windowsxp-x86-enu.exe.
  3. Run wmfdist11.exe from those extracted files.
  4. Run wmp11.exe, also from those files.
  5. Enjoy.

Encountered this issue this afternoon, so I thought I’d share a fix. Good luck.

  3. Thanks evan for this, but i tried this and when i start WMP up it says that WMP isnt installed properly

  4. Hi Ali, are you certain you ran wmfdist11.exe beforehand? WMP11 wont run properly if not.
