About the time that Evernote went to version 10.5 Scansnap integration broke.
Now when I scan with Scansnap profile "Scan to Evernote (Note)" I get a requestor saying:
Scan to Evernote (Document)
Failed tp start up Evernote for Mac.
Make sure that the selected application is installed correctly.
If Evernote is running, I get this.
If Evernote is not running it starts and I get the same error.
