This is what you need to do to straighten out your computer. Take the mouse thingy and click on the whosit, then scroll down to the third thingamagig. Highlight it and copy and paste to the whatchamacallit. It will take you to the gizmo.You can then see what you want to install. And remember, if it doesn't work for you, you can go back to the setup, and un-install the gizmo by reversing the setup thru the highlight and paste method. This works for me every time!
