Thanks Paul,

I did actually just try installing the drivers on Windows Server 2016 - and 
was surprised that they installed without an issue.

I did get the 8.2.0 drivers when we were trying Windows 10 - however work has 
requested I replace the Win10 VM with WS2016....

The install was from an ISO "Win10_1703_English_x64.iso" - and then upgraded 
to the latest release via Windows Update.

I turned on TEST SIGNING mode, rebooted Windows, installed the 8.2.0 drivers, 
turned off TEST SIGNING mode and rebooted. Windows 10 then said it was 
recovering from a problem and once it was completed, the PV drivers were 
nowhere to be found.

I do have a backup of the LV I used for it, but I'm not sure I can easily 
extract further information from it...
