I’m using Windows 10 Pro, Version 10.0.18362 Build 18362 and didn’t run into any problems installing. My scanner (Fujitsu S1500) doesn’t support Twain or WIA so in order to use this I have to “scan-to-file” and then import. Not great software compared to others that I’ve used, but will do the basics in a simple Windows XP like interface. I was even able to update it to the newest version.
By the way, my favorite pdf software to date is PDF Viewer Plus 7.1, as I mostly want to create fillable PDF files. I got it for free back when I used to use PaperPort but I’m sure there are copies available. I’ve tried the newer versions of this same software though that I wanted to throw in the garbage.
