How to not require DirectX?

I’m making a video game in UE4. I packaged the project for Windows, and it worked fine on my dev machine. However, when I tried to run the game on another machine, it would not launch, saying that it required DirectX.

Is there a way to configure the project so that it does not require DirectX? Or, is there a way to include a “portable” copy of DirectX with the game? This game is required to not install anything on the end user’s computer.

Any ideas?

EDIT: Basically what I want to do is FORCE the executable to use OpenGL instead of DirectX.

Every game needs a Graphics API. I don’t know if you are allowed to include a portable version.
Every game requires something to install I think.

Is there some way to have UE4 use OpenGL in the packaged game instead of DirectX?

Only if you go through C++ and make it so I’d think.

So… how exactly do you do that?

You rewrite the engine to use OpenGL.
