You should accept the Unsigned driver in the Canon installation. Everything will work after that. The fact it's unsigned doesn't mean it's unsafe, just that Canon have stopped getting them through the (useless) Microsoft signed procedure.
Thanks dns05. I should have mentioned that I have done just that and the software continues to load. Yet it still doesn't work. I have uninstalled and reinstalled a couple of times with the same negative results I'm afraid. Muge
