Windows Media Player: wmploc.dll version 12.0.7600.16667 instead of 12.0.7600.16415

When I attempted to play a DVD using Windows Media Player a pop-up window appeared with the following


The file wmploc.dll has a version number of 12.0.7600.16667 where 12.0.7600.16415 was expected.

Windows Media Player is not installed properly and must be reinstalled.

Do you want to install the Player from the Microsoft Web site?

                                                                         Yes           No

I clicked on 'yes' and could not find any information whatsoever on  how to correct this problem.

Can someone please give me a solution?
