7. Why is the KFI (Key From Image) option grayed out on the Admin menu?

The Admin KFI option may be disabled because You are running EzeScan DESKTOP, but you have not purchased the KFI option.

To check if you have purchased the KFI module, go to Admin Menu → and select Licensing from the dropdown. If you can see the words KFI in licensing options box then you have purchased the KFI Option.
