Wondering if they realized that I was owning a S1300 instead but nonetheless, I tried it. Then, I was suggested to download the S1300i version and provided a link for this. They suggested to uninstall the current version of Scansnap manager (I told them in the description that it was what I did at first). I guess I’ll have to forget my Scansnap S1300 on Sierra 10.12.6… This morning, Fujitsu support answered my request in a very weird fashion.
