Dear Terry Lowe, High Sierra hasn’t been published yet. Maybe SilverFast will not run with public beta versions, but it will run with the official release.
Thanks for your reply. I am using the beta version of High Sierra but on further investigation I discovered that if I completely removed the software and reinstalled the latest 10.12 version from your site it is now recognised by 10.13 beta and runs well.
