Trouble installing directx on vista?

I’m endeavoring to download directx to experiment with my emulator because at this time my genesis emulator would not work since it is lacking directx.I tried out multiple variants of directx plus none of them work; they maintain failing to setup.Is there an alternative of directx or even a variant of directx I could truthfully try

Every Your windows program computer contains DirectX.What makes you imagine you’re not often known DirectX Is there a exact problem message that you’re getting And which Genesis emulator are you currently trying in order to use

Up-date:You can’t find DirectX within the control mother board because it’s part of the operating-system.You continue to haven’t described the very problem that you’re having.In some way, you decided which you were not often known DirectX when you were having any recordings problem.We still do not know what of which problem is, other than it induced your emulator to not ever work.
