Nikon support for this model ended with Vista. Windows 9 enterprise runs correctly with NikonScan and the 1384 driver installs correctly even though the installation warns that the operating system is not compatible. I am using NikonScan with Windows 8 enterprise RTM preview. Fortunately it works, because there is no longer any support from Nikon. I am running the latest version downloaded from the Nikon obsolete products support.
