Just installed UE4 because I wanted to start learning it, yet whenever I try to start it I get an error that says this and it never starts. Weird thing is, I played Unreal Tournament a couple of months ago and it worked just fine then but now that’s not working either. I looked at all the other solutions on here and none of them seemed to help me, was hoping that there is something I am overlooking. Help is appreciated, thanks.
Hi Dammage,
Are you still experiencing this issue? After researching this issue, I found a post that read, "there is an optional update within windows update that enables level 10.0 in dx11. So you can either look for the specific optional update and try installing it (KB2670838), or even better (because there are some prerequisite updates) make sure you install ALL optional updates so your pc is current.
There is also a platform update (KB2670838) from Microsoft that users used to fix this error found here:

Be sure you pick the appropriate Windows (x64 or x86)."
Let us know if this does or does not resolve your issue.
Thanks!
