I don't think any Virtual environments support USB devices these days...so the scanner can't be installed in a virtual environment.
I just purchased the Neat Desk for $500.00 and need 64-bit support ASAP!!!!
I found this quote here:http://webworkerdaily.com/2008/07/31/neat-receipts-scanner-in-your-pocket/
"Hi, I work for The Neat Company. We will begin a 64 bit beta program in the next few weeks. If you would like to participate, please contact Jenn at jchoi@neatco.com. We do understand that this is a blocking issue (no work-around) for some of you and we are working to fix it. Providing the beta test goes well, you’ll have a solution within the next few months."
