I cannot install a driver for Canon MF4770n for windows. I get contradictory messages fro the Canon website when I try to install driver. One says unable to install drriver and another cannot install driver because it is alreaady installed which it isn't. I trry the override feature but that doesn't work either. The software that comes with the unit does not give me instructions, just a bunch of files which are meaningless to me. I am very frustrated and would appreciate help.

Uninstall a Driver
When you need to uninstall a driver completely, the best and safest method is to use the device’s uninstaller program (if it has one). If you added the device to your system through an installer (as is the case with most graphics card and sound card drivers, for instance), you can uninstall it just as you would any other program.
Sometimes devices won’t have an uninstaller, or the uninstaller will not appear in the list. In those instances, you can use the Device Manager to remove the driver completely.
After you roll back or uninstall a problematic driver, you can try downloading and installing the latest version from the manufacturer’s website, or try a specific version that previously worked to get your computer back on its feet.
