Windows Media Player demands reinstallation

Some of my colleagues and I have been encountering an error with Windows Media Player. The error keeps saying the WMP should be re-installed for the different version. Moreover, it states that the system needs a different version of WMP and its reading a different version, but I don’t want to change my WMP again.
Help me out here please. My colleagues and I will be eternally grateful.
Thanks!

Windows Media Player
The file wmploc.dll has a version number of 11.0.6001.7000 where
11.0.6002.16489 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?
