Rick, Both computers need the TeamViewer software. The host computer (mom) will find an ID # and password # when they open the program. She will give you the ID # and you will enter the ID # and check the "take control" You will then be able to see her screen and move the mouse. It is just like you are in front of her computer. You may find it slow depending on the internet speed that you and she has. But it will allow you to help her. Good luck.
