I have re/re the software with no success. I have win 7/64. Other functions on the machine work very well. I have used software downloaded from Canon as well as the original disk, no results. I do notice a reference on the operating screen of the printer that makes reference to a USB connection but Canon manual advises against combining USB and WiFi.</P> Sun, 20 Oct 2013 05:05:23 GMT Denis 2013-10-20T05:05:23Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MX870-all-in-one-MP-navigator-will-not-launch/m-p/45011#M27882 <P>The MP Navigator will not launch.
