I think maybe UE4 does not support 32 bit, the editor does not, (unfortunately the game is made in Unreal Engine, and not Unity, and games made in UE4 require 64 bit as the minimum, so if that's the case, I suggest you upgrade to 64 bit, get Media Creation Tool.)
You really should make it 64 bit, recent games do not support 32 bit anymore, games that supports 32 bit are pretty rare nowadays (except indie games). Use Media Creation Tool.
