: Add/Remove Office Keyboard Software and Re-Install
A: After you have installed the Office Keyboard software, the Office Keyboard Icon will display on system tray. If you want to re-install the software for any reason, you must delete the Office Keyboard software drivers from your system. Right-click the mouse button on the Office Keyboard Icon and choose EXIT. Next, open the Control panel from the Start menu and then select (Add/Remove) to delete the Office Keyboard software. This will remove the drivers from your system. Now you must restart your system and re-install the software drivers.
Note: You must use this procedure if you want to upgrade your Office Keyboard functions or the software does not work properly.
