DirectX is up to v10 or 11 now. Go to their website http://www.microsoft.com/games/en-US/aboutGFW/pages/directx.aspx and download the newest version, that should fix your issue. Also since the PC's are new make sure you have *all* of windows updates, since I think direct X is covered in those. If that dosnt fix the issue please try and screenie, or type out the error since DirectX has a few different things that can go wrong with it.
