How do I enable touchpad vertical scrolling?

When I go to the Control Panel > Mouse, I get an error message that says that my laptop is not recognizing my touchpad. Attachment 356752 (http://ift.tt/1Eh1jkV) It still lets me open the configure window if I hit "no," and when I go to Device Settings > Scrolling > One-Finger Scrolling, it does not let me check the "Enable Vertical Scrolling" box....
