Hi, I upgraded to 8.1 from 8, and can no longer use my scanner. My scanner is part of a Canon Pixma 470 all-in-one. (Printer jammed, haven't tried using it). I keep getting the error message, "The scanner driver supported by this software is not installed. Install it and retry."
Today while on the phone with Canon, I uninstalled and reinstalled both the driver and the software several times, doing all they suggested, such as using IE instead of Chrome and running as administrator. I also tried Troubleshoot Compatibility, and got the message "incompatible program." I don't have any antivirus software as far as I know, but she said if I had any in the past it could still be there. I have no problems installing other programs. The customer support had no more advice.
The printer is not showing up in Devices.
I assumed the problem was from going to Windows 8.1, but I also tried installing MP Navigator and software on my other computer that has Win8, used IE, never had antivirus on that machine (which I rarely use) and I got the same error message. So I think the problem is with the Canon MPNavigator itself.
Any suggestions appreciated! Thanks.
