After downloading the visioneer 9420 driver file (found on the visioneer site, but before installing it, remove your old 8100 driver, then install the 9420 driver by running the .exe file you downloaded from visioneer. Then, use Device Manager, go to -update device drivers and in the listing you should see the 8100 listed. Double click on it, click on -update, go to -browse my computer for driver software, then go to -let me pick from a list, then you should see the 8100 scanner appear, click on it, click on next, and then it will install the 9420 driver. My 8100 is working great on a vista system. Don't get rid of that scanner! It works!

Are you talking about the $100 program? I don't see that as a fix. Or what download are you talking about?

Tried your suggestion on Vista. Can't make it work.
Just install the 8100 driver as is. Then do NOT use Paperport or any
other software that came with the 8100. Instead, just scan documents
from within Adobe Acrobat and/or photos from within Photoshop. It
works, because Adobe stuff DOES work in Vista. In fact I'm scanning
stuff with my old 8100 into my new Vista machine right now as we
speak--both documents and photos, and it's working great. The output
is pdf files and jpeg photos. Perfect.
Does not Work ???
