I had a problem with this scanner trying to install as if it were a Canoscan LiDE50. I adapted this guy's methods (Windows 7 – Canon LiDE 35 installation fix | Bull's Rambles
) and they worked for me.
I've reprinted them below but changed what I needed to to get mine to work. Hope this helps someone
Open device manager locate the scanner device (it probably has a yellow exclamation mark next to it).
Select properties then update driver
Choose Browse my computer for driver software then Let me pick from a list of device drivers
on my computer.
Look for Canon Inc. in the manufacturer list, then select CanoScan LiDE 35, instead of the default CanoScan LiDE 50. <-- you may have to first download and install this driver from Canon's website
Click next and ignore any warnings about the driver not matching your hardware (you shouldn't get these anyway), that’s it all done your scanner should now work.
