wrote: I have a Canon imageCLASS MF4570dn. I switched to Windows 10 in December & have been using Toolbox with no problems until yesterday. Yesterday it gave me a message that a compatible scanner was not installed.
I tried everything that I could think of with no success, even installed with the old Canon CD. On the old CD, I dicovered "Presto!" and installed it. "Presto!" had no problem finding the scanner, and in fact used the "ScanGear MF" window that I've come to love.
So I thought that "Canon MF Toolbox 4.9" must be a 'launching pad' for "ScanGear MF" and the problem is with "Canon MF Toolbox 4.9".
In a nutshell the following finally worked for me:
-Right mouse click on "Canon MF Toolbox 4.9"
-Click on "Troubleshoot Compatibility"
-Click on "Troubleshoot program" (NOT "Try recommended settings")
-Select only "The program requires additional permissions"
-Click on "Next" button
-Click on "Test the program..." button
-Give Windows "User Account Control" permission (the flashing shield that appears in the Taskbar)
-Click on "Next" button
-Click on "Yes, save these settings for this program"
-Click on "Close"
"Canon MF Toolbox 4.9" will now Run as Administrator
Hope this helps some of you
Hi,
My printer is Canon i-SENSYS MF4890dw
I got this problem today after an update (Windows security and bunch of other updates). Since none of the previous solutions worked for me (even mine, which solved problem twice) I tried yours. Now I can scan documents from computer in MF Toolbox (remote scaner mode on my Canon Printer) but when I try to scan directly from Canon device I get message that there is no compatibile MF Toolbox installed on my PC. Do you have such problem?
I'm about to give up...
