I've gone through this problem for a few years with new Macs without seeing any resolution on here. I found this firmware update on Fujitsu's website that solves two problems. 1. I get a functioning $400+ scanner back. 2. It solves the 64 bit macOS problem for future macOS versions. It's a firmware upgrade that changes the Evernote edition into a regular ix500. WARNING, you lose some of the automation between the ScanSnap and Evernote, but this page explains what the losses are before you decide to upgrade the firmware.
Error when installing ScanSnap Evernote software: "Unable to locate the installer package"
