[Diogenovich]

ok so my friend baught me arma 3 beta and i Really wanted to play it, so i installed steam and downloaded the gift i got, so i pressed play and it gave me the message : "The latest Version of Directx is required to play this game" so i ran DXdiag and it tells me i have DX11 and i didn't knew what to do, so i opened arma 3 AGAIN and now i pressed the site steam linked me to, it was microsoft.com/windows/directx but since this site no longer exists it redirected me to Xbox Marketplace.my Nvidia drivers are up to date, but when i try to install directX it just doesn't work.
