Vista looked for the scanner driver and found none. It directed me to the Epson site.
I downloaded the driver and saved it to the desktop so I could find it. The icon is covered by the small MSFT security shield. When I right click on the Epson icon and click on OPEN, I get publisher could not be verified, I click RUN, then I get "allow" or deny. I click allow. It is a win-zip self extracted file. It says the file contains the Epson scan ICM updater V.1.20 for Windows. This supports Vista 32 and 64 bit.
I click ok and it extracts the file. Then I get "this program installed correctly". I click on that and get nothing, I'm back to the desktop and the only option there is, is to start over. I am getting a message that
"this file does not have a valid digital signature. That box repeats that the publisher is not known. Only option is to click RUN again, and I'm back in the same loop. The scanner was turned on before installing the disc. It is the Epson Perfection 3170 photo.
