If you get the error “xinput1_3.dll not found”, whether you’re using GameMaker Studio or any other application, the answer is simple, you need to fix your DirectX install. The link below works great. I had this issue and after running the following (it’s a simple install) things worked great for me.
In my case, I couldn’t get GamePad support in GameMaker Studio, I was getting the error message “xinput1_3.dll not found. Gamepad support disabled”, so that’s what I did to fix it.
