Minolta DiMAGE Scan Dual III

How do you revive a piece of hardware that was manufactured when most people could only dream of a digital camera? When Windows 98 was the ultimate operating system and memory was in mega- rather than gigabytes. The Minolta DiMAGE Scan Dual III was the ultimate photonegative and dia scanner.
After purchasing my first digital camera, the precious machine was gathering dust in a closet. Too expensive to throw away. Too obsolete to find a driver to make it work with the latest hardware. With somebody really wanting a print of the image below, I had to find a solution.
1. Install the original driver leaving the scanner unconnected.
2. Connect the scanner and let Windows 10 do its discovery work.
3. Disable driver signature verification for 64-bits Windows 10 versions; by default 64-Bit editions of Windows require digitally signed drivers. The problem is that older devices use unsigned drivers.
4. Download a more recent .inf file for Minolta scanners and update the driver for the scanner from Device Manager in Windows (using Google, it is easy to find an alternative version of the file).

All links are still working and all drivers referred to are still downloadable from, though you have to fiddle a little bit with the Konica-Minolta site. Should they fail, drop me a line in the comments below.
