Maybe run dxdiag to check your directX installation. If you are using Win10 (with latest updates, and at least 1803) it should show up as dx12. You should not have to download directX redistributables, it should just come with Win10. If you are still on Win7 then maybe it's time to upgrade to win10.Otherwise, contact Oculus Support and include your logfiles. Good luck mate.
