I am having this same issue, but I am a Premium member of Evernote and a very dependent user. I have two ScanSnap printers -- one at my home office (Evernote version) and one at my "office office" (ix500). Both of them stopped working when I upgraded to Mojave, but I was able to easily fix the ix500 with a software/driver upgrade. When I try to reinstall the Evernote for ScanSnap driver/software, I get a message saying that "installation failed." Fujitsu is not able to support the scanner and gave me a phone number to call which sent me to Evernote billing. I submitted a support ticket, but the ticket forces you to choose a device about which you are writing, and the scanner isn't an option. I had to choose "Evernote for Salesforce" in order to submit the ticket, so I have no idea if I will get a response. Help!! I spent $500 on this scanner and don't want to have to spend it again because of compatibility issues. #beggingyou #anyoneoutthere #donthavetimeforthis
