i dont think its possible to install individual versions of directx. the updater doesnt allow u to pick a specific update to install. i think what he meant is to install all the latest directx updates (update all the directx components) for your specific os as released by microsoft.
Just as Lady Femme said you can not install a down rev. version of Direct X. So if you have direct X 11 you can not go backwards to 4.
