Problem with Age of empires 3 help please

[Onolly]

well i just instaled aoe3 and when i said "launch" it did this thing with compadability. i first said to check for solutions but it couldnt find any, so i said "run any way". when i do this the screen changes and says "adjsting screen colour" or some thing like that. then a error message pops up saying "MSXML 4.0 has not been instaled correctly" so i have no idea what that means and all i could say was "ok". i reinstalid the game but it still dosnt work. please help me.

P.S i am sorry about spelling and grammer
