Removing XP Registry Settings after DigiClassic Driver Uninstall

I would like to CLEAN my XP system of Digi Classic keys. I have Uninstalled the DigiClassic driver, and removed the card and rebooted, but find that HKEY_LOCAL_MACHINE\System\ControlSet002\Enum\Classic and its subsidiaries cannot be removed. Is there a trick?

I am supposed to install the Digi software a certain way from the instrument vendor but can’t due to its detection of a pre-existing install.
