For those wishing to get their Nikon Coolscan film scanners working under either Vista or Windows 7 64-bit editions here’s a solution…. Note - This fix applies to the 4000, 5000, 8000, and 9000 series scanners. I can't guarantee older scanners will work but it's worth a try. If not, check this post for help or tips for older scanners. And credit Steel Chn for the inf file. I'm just providing an already built modified file that includes the Nikon 5000. Now... Before you get started: Remove Vuescan if installed. You can re-install it after these procedures. 1- Download this file Nikon Scan 4.0.3 from Nikon's site drivers for Windows Vista 32-bit. Yes, Vista 32-bit. 2- Then download this zip file: scanners.zip from here. 3- Extract and save the scanners.inf file to a location or folder of your choosing... Example: I created a folder called Nikon Files. After I install the Nikon Scan software, I'll then place the Nikon Files folder inside the NKScan4 folder located at...
C:\Program Files (x86)\Nikon\NkScan4 - Thus the NKScan4 folder now contains the Nikon Files folder and will look like this... C:\Program Files (x86)\Nikon\NkScan4\Nikon Files
4- Now install the Nikon Scan software you downloaded and after the installation, go to.... C:\Program Files (x86)\Common Files\Nikon\Driver\Scan1394 (see note) and copy this file NKScnUSD.dll to the same folder (Example: Nikon Files) that the scanners.inf file is in.
Thus the Nikon Files folder should now contain these two files... NKScnUSD.dll and scanners.inf
NOTE: If your scanner is USB than the folder will be ScanUSB instead of Scan1394. Once that’s done…. 5- Power up the scanner and make sure the Firewire or USB cable is connected to the computer. 6- Cancel any dialogue boxes looking for drivers if they appear. 7- Go to Device Manager – Control Panel, Device Manager and look for the "Unknown Device" (your scanner) with the yellow triangle. 8- Right click on it and choose "Update Driver Software" then choose "Browse my computer for driver software" 9- Click "Browse" and find the location or folder where you put the scanners.inf file. Example: C:\Program Files (x86)\Nikon\NkScan4\Nikon Files and click "Next" This will/should install the driver (scanners.inf) you extracted from the zip file for your scanner. 10- That’s it – Your Nikon Scan software should now be fully functional.
