Canon MP145 MP Navigator Scan Failed

OS using Windows 7 (64). Scanning from Control Panel is alright, but from MP Navigator 3.1 show “Scan failed…”.

The solution that worked for me is to append into the PATH environment variable the following path (YMMV):

C:\Windows\twain_32\MP140 series

After that, restart MP Navigator 3.1 and you should able to scan. Good luck.
