CTL-672 Cannot install new driver because old one still exists on Mac

Trying to install driver for Wacom One CTL-672 tablet but displays message to remove old driver first. I had a Wacom Bamboo many years ago but do not have the Wacom utility to remove old driver. I have deleted any file that contains 'wacom' but still displays message to delete old driver first. Contacted Wacom but they suggested deleting 'wacom' files but still not allowing installation of new driver - any help gratefully received!!
