wmp 9 instalation problem

I was trying to install windows media player
@ the end of the media player 9 instalation this following
message pops up...."it was not possible to
complete setup windows media player 9 series was not
instaled. to update windows, run windows media player 9
series setup again." i ran it again and the same thing
happened, what do i do? suggestions anyone? cause although
i can keep running it over and over again nothing seems to
happen cept my patience runs thin, is this like a test on
humans microsoft is running? to see how long it takes
before we through a brick through the screen? help?
PLEASE? ANYONE?
