Puzzling WMP error message

I have WMP 10. Help>About says Version: 10.00.00.4036

But if I go to Help>Check for Player updates, I get a window titled
'Windows Media Player 9 Series'

with a message that the Setup Wizard has encountered a problem:

"More recent Player already installed
Your version of Windows on this Computer already contains a more
recent version of Windows Media Player. Windows Media Player 9 Series
setup will now exit."

What's going on here please? How does WMP 9 get into the act?

Also, assuming I find a way to do so safely, is there a consensus on
whether it's worth upgrading to version 11 yet, i.e. is it stable?

Quit clicking the "check for updates".....WMP 11 is really improved WMP10,
also with WMP11,its uninstallable thru add/remove,WMP10 is not.11 is as
stable as 10 if not more.
