It finds all the limits, but persistantly gives the error "Can't move driver file", even in PC Safe Mode when Win Defender is switched Off. If I restore the ATI WHQL driver supplied with Win 10 or install an older 2016 driver, the patcher gives another error "The driver file is too big". Cleaning GPU drivers with DDU and reinstalling any doesn't affect this error.

Those are both unusual problems. The "Failed to move driver file" error has never been reported before. Try removing this folder if it exists: C:\Windows\System32\drivers\atikmdag-patched

The current version of the patcher should work fine with older drivers. The "Driver file too large" error should not happen with older drivers because older drivers are not large enough to trigger the error. I can't think of anything that would cause this error if you're using the current patcher.

The 1st attempt went through OK, however when the driver get reinstalled the card was still blocked by Windows with Error 43, so the patch was apparently not fully applied despite no Patcher error.

If the patcher didn't report an error, then it applied successfully. The patch has to be applied every time the driver is updated. Windows Update has a nasty habit of updating the driver in the background even while you're installing a newer driver. Then when you reboot, it actually boots the older driver. It's best to disconnect from the Internet until after you've installed the new driver and rebooted.
