Regardless of what video card you have installed use DDU (
Display Driver Uninstaller ) to uninstall / cleanup your current driver.
To do so you must reboot into safemode then run DDU and uninstall the Display Driver.
I assume the reason NVCleanstall is failing is because Windows is installing the default display driver for your Graphics Card before you can run NVCleanstall.
One way around this is to download the latest display driver for your card and then let NVCleanstall build an Install package you can run after cleaning with DDU.
So after cleaning with DDU and shutting down you must disconnect from the internet and then reboot to install the driver created by NVCleasntall.
Then you can connect the internet again and any further driver updates using NVCleanstall will work just fine.
