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.
