You simply install direct X, It should come with the media, You have to have a card that supports the direct x featured and to use feature direct X 10 you need vista, for direct X 11 you need windows 7. I do not think there is anything requiring 11 though.Check your graphics card support and make sure you have installed at least direct x 9c redistribute, It should be in the installers on your disk.
