NikonScan4 in Windows

Version 4.0.3 was the final release of Nikon's Coolscan Windows scanning application. It was intended for the 32-bit Windows Vista but also runs without modification in the 32-bit versions of Windows7 and Windows 8. Nikon never produced Coolscan drivers to run under 64-bit Windows but modification is straight-forward and is described below.

NikonScan4 in MacOS

As stated in the above article, NikonScan version 4.0.2 was the final release of the MacOS software and the last supported MacOS version was 10.4.11 running on PowerPC Mac. There are some reports of users running later versions and different hardware but possibly not reliably.

NikonScan in 64-bit Windows - Detailed Instructions

For Windows XP and Windows 7 32-bit PCs, installation of the Coolscan drivers is carried out as part of the installation of the NikonScan4 software. No special procedure is necessary.

For Windows 7 64-bit, Windows 8 & Windows 10, the following procedure should be followed

Step 1
First, copy the un-zipped modified drivers to any permanent location on your C-drive (eg create a folder "Coolscan" on C and drop the drivers in it).

Step 2
If you are installing on a Windows 7 64-bit PC then jump straight to Step 3 because Step 2 is unnecessary.

For Windows 8 & 10 PCs you must now disable "Digitally Signed Driver Verification" since the Coolscan drivers are not "digitally signed":

Windows 8
Control Panel / Change PC Settings / General / Advanced Startup
Press "Restart Now".
PC reboots
Choose "Troubleshoot"
Choose "Advanced Options"
Choose "Startup Settings"
Choose "Restart"
PC reboots
On "Startup Settings" screen choose option 7 "Disable driver signature enforcement"
PC reboots into required mode.

Windows 10
Settings / Update & Security / Recovery
Choose "Advanced Startup - Restart Now"
PC reboots
Choose "Troubleshoot".
Choose "Advanced Options"
Choose "Startup Settings"
Choose "Restart"
PC reboots
Choose option 7 "Disable driver signature enforcement"
PC reboots into required mode.

[Note that your keyboard needs to be "live" to allow option 7 to be selected; some wireless keyboards may not have connected at this point in the restart sequence and if this is the case, you will need to restart the procedure using a wired keyboard]

Step 3
Open Device Manager
Connect and switch-on your scanner.
An "unknown device" should appear under the "Imaging Devices" section (expand as necessary).
Right-click on the unknown device and select "Update Driver".
Select "Browse" and navigate to the previously created folder containing the modified drivers.
Click OK and dismiss any warning messages.
The unknown device in Device Manager should now indicate the exact Coolscan model attached, eg "Nikon SUPER COOLSCAN 8000 ED".

Step 4
If you have any other Coolscan scanners, connect them in turn and repeat Step 3; every model of Coolscan must be separately registered in this way.

Step 5
Reboot the PC.
