I don't have my installation CD :-(

Looks like the older visioneer scanners are not compatible past win xp...

I went herehttp://support.visioneer.com/products/9000/downloads.asp They don't have any drivers for Vista you can try talking to customer service but you might have to buy a new Scanner! Sorry :(

Help is here,
You have compatibility problems with visioneer and Vista, I helped a few people last week with the same problem.
I recommended them too www.cnet.com for the latest paperport download and got my Fixya button pressed.
Please remember to rate my efforts,

Hi!

Dont know if you solved your problem...but here is the drivers for your scanner anyway

Good luck

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!

I had the same problem. After I downloaded the driver I disconnected the scanner.
Then restarted the PC and after up, plugged in the scanner to my USB, Windows found it and installed it. Now the system recognizes the scanner. However, I am still
looking for a user manual to know how to use the scanner. I performed a scan ok to the desktop, but cannot find the document on the system. ed

Verified to work with Vista Home Premium x64 (should work for x32 as well):


1. Make sure your 8100 is unplugged.


2. Go to Visioneer's website and download drivers for the OneTouch 9420 scanner:

3. Install the drivers. Nothing will work... yet, don't worry.


4. Now plug in your 8100. You'll get a message saying that Vista wants to find drivers. Select "Ask Me Later" or just cancel.


5. Next, open up Control Panel and then Device Manager. Find your 8100 in there (probably listed as "Unknown Device") and then right click on it and say "Update Driver Software". Now click "Browse My Computer For Driver Software" then "Let Me Pick From A List Of Device Drivers On My Computer".

6. Scroll down to "IMAGING DEVICES" then find Visioneer, then you should see the "Visioneer 9420" driver. Select it. You'll get a warning from Vista, but continue anyways. That's it... everything should work.

Unfortunately this scanner is at end of life and I do not think you will find any drivers for Vista.

You need up-to-date driver software to detect it. Check your driver software availability.

"download"?? You don't download, you install. Have you considered that the scanner might not be compatible with Vista? Here's the Visioneer site: http://support.visioneer.com/products/home/EOL/8100/downloads.asp
