My problems are worse. I tried reinstalling MF Toolbox on my D530 and it wouldn't reinstall.
I tried calling Canon customer service. There should be special place in hell for CS reps that simply lie to you to get you off the phone.
This jerk kept insisting that my only problem was that I was using a 6 foot USB cable instead of a 3 foot one. I said I had never heard of that on any piece of equipment and he told me that, yeah, it was all over their internal cust service resources that Win 10 had to have only a short, 3 foot USB cable. When I said I would have to rearrange my entire office, he said that was the way it was. Needless to say, after I rearranged the office to get a 3 foot cable MFT still didn't work.
Then I tried to uninstall MFT so I could reinstall it, and it would not uninstall. I had to use Revo Uninstaller to scour my system to remove all traces of MFT. Then it wouldn't install, hanging at the 'Process Initiating' screen, on both the current and previous versions of the install files. And, yes, I rebooted on each step along the way.
Now I can't use my scanner and there's no way to test the solutions offered here because Canon's software won't install and won't uninstall on my Win 10 64 rig.
Any suggestions?
