Hi, have you installed Synaptic Package Manager? I was disappointed that it was not present as it had been on all previous releases of Zorin. Search for it in Software and install it. Once installed search for touchpad or synaptics and you should have:
xserver-xorg-input-synaptics-hwe-16.04 [version 1.8.3-1ubuntu1~16.04.1]
installed items have a filled green box in the 'S' column.
I wanted to post images but it would appear the forum capacity is full.
Also see if this helps [taken from

"Disable the touchpad while typing, with a delay of one second
16. It's pretty useful to disable the touchpad (trackpad) of your laptop during typing, and tweak the delay. Especially on small laptops.
That's easy to configure:
Note: the tweak I'm going to describe, only disables the touchpad functions of tapping and scrolling. Mouse pointer movements are still allowed. The delay is one second, which should be unobtrusive.
Create an adapted startup application:
Click on the grey Ubuntu logo (Dash home). Query: startup.
Click Startup Applications - Add
Fill out the fields as follows (use copy/paste, that's easiest):
Name:
Syndaemon
Command:
syndaemon -i 1.0 -K -R -t
Comment:
Disable touchpad while typing, with a reasonable delay and only for tapping and scrolling
Click Add and then Close.
Reboot your computer.
Finally, check whether it's working, with the help of the following terminal command (copy/paste the line below in a terminal and press Enter):
ps aux|grep syndaemon
Note: this is a user preference, so repeat this in every user account."
