Just updated to win 10, toolbox would not work so scanner didn't function MF 4880. Attempted to uninstall all drivers so a fresh install might work, uninstalled all drivers so that no printers showed in device manager or devices and printers. Attempted install of current driver package from Canon and get error MF drivers already installed. Please uninstall drivers before running installer. There is nothing obviously file wise left regarding printer. There must be a file left somewhere that makes the installer think the driver is still installed. Any idea what file is preventing the installer from working??? Thanks
