I can help you with that:
- read this: Axel Rietschin: Nikon LS-40 / LS-50 / LS-5000 Scanners on Windows 8.1, Windows 8, Windows 7 and Windows Vista 64-bit!
- but get the last version of Nikon Scan (4.0.3) here: https://www.nikonimgsupport.com/ni/NI_article?articleno=000002646&configured=1&lang=en_US because the link actually in the blog post doesn’t work.
- carefully follow the instructions in the blog post.
It works fine on my Win 10 machine, currently on Win 10 v1903.
