My touch pad is not responding to clicks.  It's fine with tapping and moving the cursor, but it won't respond to a left click.

I want to upgrade the driver for the touch pad to see if that solves it, but I have some sort of issue there.  In my programs I have "Synaptics Pointing Device Driver - 19.0.14.1" which has been corrupted - I can't uninstall it because the path is not found.  Can anyone direct me to a link to that driver?  One solution might be to re-install it, but I can't find it anywhere reliable online.  Alternatively, maybe there's a better Synaptics driver I should use?  Do I need a Synaptics driver or am I covered with the Microsoft HID driver?
