Never heard of unreal engine before. trying to launch trainsimworld getting unreal engine 4 crash reporter. what do i do

Dont know anything about this system or I even had it. Can someone sort it out for me. I dont know what version of this thing I have.

You should contact the developers of Trainsimworldn (the app uses Unreal Engine, but is not the Engine what is crashing the app but the app itself). Unreal engine is reporting probably an issue in the code of the app you are trying to lunch, but its not something Unreal Engine developers can solve.
