After last update on Win 10 (64) my Navigator (Scanning) stopped working.
Couldn't communicate with the printer.
Use the scanner function direct on the printer.
After scanning my MP Navigator Ex version 2.05 opened and I was able to save the img.
My shortway for Navigator disappered but I found "C:\Program Files (x86)\Canon\MP Navigator EX 2.0\mpnex20.exe" and I created a new.
