|If you have checked your downloaded version ZipCentral for infections, that will do all you need.|
"So I extract all of the zip files into a different folder first"
In your Programs folder, right click & make a new folder, name it > VIAUnichrome driver.
Now run ZipCentral & tell it where that new folder is.
"and then run the setup.exe"
"This will execute it to where it will be needed to go?"
Reboot when it's finished & tell us if it is happy.
I will take you into Device Manager next, if the comp is behaving.
