Win64-shipping.exe not working

I have packaged game like game-win64-shipping not working comes error that failed to open descriptor file. When remove that win64-shipping it works okay in my computer but not in steam, steam may need that gamename-win64-shipping.exe or then need advices

I did that on Steam and had same issue while trying to start the game. What I had to do to fix was:

  1. Games → Add a Non-Steam Game to My Library…
  2. pointed to “~\Program Files\Epic Games\UnrealTournament\Engine\Binaries\Win64\UE4-Win64-Shipping.exe”
  3. then RMB on new list element UE4-Win64-Shipping → Properties
  4. SET LAUNCH OPTIONS…
  5. added " unrealtournament", then OK
  6. worked from now
