Use your mouse to click on the very first box (top left). Then use the controller to carefully press the button you want for each slection. I suggest you use the d-pad buttons for Menu options. It will automatically advance you to the next option as you press buttons on the controller. If you mess up one, just start over, or use your mouse to select the box where you went wrong.
After all the boxes are filled, just close the window. It will save automatically.
Hope this works for you.
You can always go back and try another setup.
