Currently using Coolscan 4000 firewire and NikonScan 4.03 with Windows 10 64-bit OS. Here's how to do it. Go to Nikon Coolscan, Nikon Scan, Driver: 64 bit Windows Vista / Windows 7 / Windows 8 for information on updating NikonScan driver. The inf file that you want to update for firewire is Nks1394.inf. Unfortunately the driver is now an unsigned driver according to Windows. Go to Windows 10: Disable Signed Driver Enforcement to get instructions on disabling signed driver enforcement. It all works. Thank goodness for helpful people on the web to continue to help patch the Nikon software.
