Fix it for me

On 64-bit Windows operating systems, this Fix it solution can only fix the problem if both the 32-bit and 64-bit versions of the Windows Media Player are installed on the machine. The command "unregmp2.exe /UpdateWMPVersion" can only update the registry key value of HKLM\SOFTWARE\Microsoft\MediaPlayer\Setup\Installed Versions\wmp.dll, it does not update HKLM\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer\Setup\Installed Versions\wmp.dll.

To fix this problem automatically, click the Fix this problem link. Then click Run in the File Download dialog box, and follow the steps in this wizard.

Note This wizard may be in English only; however, the automatic fix also works for other language versions of Windows.

Note If you are not on the computer that has the problem, you can save the automatic fix to a flash drive or to a CD, and then you can run it on the computer that has the problem.
