Windows Media Player 11 and Sansa Players

Over the past year of so I've heard about a lot of "Synchronize to Continue..." error messages on Sansa players. A colleague sent along the following suggestion to roll back Windows Media Player 11 to the previous version of WMP (usually WMP 10). I am very happy to say that the patron having trouble with the Sansa M200 player now has a workable player again after rolling back to WMP 10.


Here are the full instructions.

Thanks, James!

Note: If you remove Windows Media Player 11 and the Windows Media Format 11 Runtime, and then encounter error C00D271D ("A problem has occurred in the Digital Rights Management component. Contact Microsoft product support."), you might be able to resolve the problem by installing the Windows Media Format 9.5 Runtime. For information about installing the Runtime, in the Microsoft Knowledge Base, see article 891122, "Update for Windows Media Digital RightsManagement-enabledplayers."

You might not be able to roll back to a previous version of the Player if the hidden folder $NtUninstallwmp11$ is deleted from your computer. Some non-Microsoft programs (such as CCleaner) delete this folder in an attempt to remove unwanted files from your computer.
