Hi James,
Thank you very much for your help. But I have already found solution.
I tried many times what you suggested but in vain. I appreciate the Cannon Technical team who did their best to fix my problem online. The specialist from cannon uninstalled the scanner driver and reinstalled repeatedly.But the specialist couldn’t install scanner driver on my computer. Finally, the specialist gave up saying that scanner can’t work on my computer. He suggested to contact Microsoft to solve this issue. But I never give up.
I got windows 10 repaired using back up in my computer, uninstalled the scanner driver and reinstalled it from Canon website. It did work. I appreciate everybody for their suggestions offered.
