The switch has not been easy, possibly going from Vista and switching to 64 at the same time has added extra hurdles for me - or maybe it's just because I'm not very good with PC's

Anyway, after the clean install, and many an evening re-installing everything, I thought I was done.... until I remembered I hadn't had to use the scanner yet. I was reminded by a little icon on the taskbar which said it was installing drivers for it - unprompted and yet days after the original install of 7? And it just kept installing, and failing. It's a Canon Lide 90 by the way.

Started off with the disc that came with it - no go. Tried compatibility options and 'run as administrator' and eventually got most things to load/install but it wouldn't work - didn't see the scanner.
Downloaded new drivers from Canon and treid them too but as soon as I plug in the USB lead up pops the icon on the taskbar and off it goes, installing until I pull the cable, never getting there, and never actually working.

How do I clear out all the old drivers? I have uninstalled via the control panel but I wonder if there's old stuff left? Any suggestions?
