I try to install my scanner (a Canon Canoscan 5600F) on my MacBook Pro (Sierra 10.12.6).
I installed both drivers I found on Canon website (generic and TWAIN) compatible with this model and with OS X 10.12.
Scanner works correctly.
Then I tried to install the Canon scanning software MP Navigator EX 2.0.8 (from the same webpage) after checking for compatibility again. A restart was required.
When I try to launch MP Navigator, I just got an error message telling that the right driver recognized by this software is not installed.
I uninstalled everything (software and drivers) and reinstalled again, double checking for compatibility. Same issue…
Maybe anybody got the same problem and found a solution?
