Software Driver Update

Uninstall any other pointing device software before updating.

Uninstalling Driver
Right click the mouse icon on the task bar, click Close to shut down the driver first. Then go to Control Panel, Add/Remove Programs, select the driver, click Change/Remove, and click Remove.
 

Incompatibility
If the driver update does not solve your problem, the driver may be uninstalled. The VerticalMouse can still function as a  2-button mouse without the driver
