Why wont it let me highlight my curser?

I was told that I can make a highlighted curser using this program. Now ive did everything I was told to do, but when I click "ok" I dont get my highlighted curser and I wanna know why.

Maybe you need to try to "Google" instructions or maybe try to type that in "YouTube" You would be shocked what might come up. That's what I would do. Maybe call computer Co. I hope these ideas help. :)
