Program cant start because api-ms-win-crt-runtime-l1-1-0.dll is missing ?

Hi Tallon --

Are you using the itch.io app? If so, I *think* it should set things up properly for you.

Barring that, try the instructions here, just after the big screenshot, re: UE4PrereqSetup_x64:

I installed that first, Ended up having to install KB2999226.exe from the M$ site something to do with broken installation
