Thanks for the reply, recommend you to install all the updates from Windows. Also, uninstall the driver again from the device manager and delete the driver when prompted. 

Restart the computer and install the driver again from our website. If the issue persists, open device manager and check if the touchpad is disabled or enabled. If it is disabled, please enable it. 

Let me know how it goes.
