Required dependencies for UE4 games.

Is this known to work properly when running from Steam? I’m pointed at the root exe, but new players still have issues getting it to run for the first time until they run UE4PreReqSetup.msi.
I also tried including common redists through steam, but it still appears to be missing something. I made a post here regarding that: What gets installed with UE4PrereqSetup_x64.exe? - Platform & Builds - Epic Developer Community Forums

If you cannot assist with this, would you be able to point me to a dev who could?

Thanks!
