When the PC restarts select the option to disable device driver signing enforcement (option 7).In the new interface that appears select “troubleshoot”.Under “advanced startup” select “restart”.The older vuescan driver works with this but like the modified Canon driver, device driver signing verification needs to be disabled temporarily to install it.

Newer versions of Vuescan (when paid for) will work, but Vuescan has it’s own app which doesn’t work well for scanning slides, so I wanted to use the Nikon software directly. The Nikon scanner doesn’t have a modifiable driver but I was able to get it working with an old version of Hamrick Vuescan which installs a driver which works with the Nikon scanning software.

See below for precise step by step instructions. There is a modified driver for the Canon which worked with windows 7 and the same driver can be installed on windows 10 via the “have disk” method in device manager, as long as device driving signing is temporarily disabled first. The 2 scanners in question in my case are a Nikon slide scanner (CoolScan IV ED) and a Canon Lide 50 flatbed scanner.
