Just bought a new Canoscan D1250U2. The computer detects the hardware correctly everytime, but whenever I tried installing the driver, it says 'class installer denies installation or upgrade of device' after all files are copied. I opened device manager & the scanner is there, but it's disabled and it says in the box that the driver will be uninstalled when I next start up the computer.
So the driver is copied, but for some reason it uninstalled itself after copying it. It's the same whether I load all programs at startup or in 'selective loading' mode. I also tried installing with the digital signature detection ignored, but no joy.
What's wrong?
