The Scansnap fix below worked for the s510. It might work for the s500, s300.
All free advice from the internet should be considered to be caveat emptor. If something horrible happens, how can I pay for it if I didn't charge anything for what was truly believed to be solid advice, right?

Post-Install Tips:
If you are unable to scan, you can try exiting the ScanSnap Manager from the bottom right hand corner of your computer screen and restart it from Start/programs/ScanSnap/Scansnap Manager.
If you are still unable to scan, run the SsDrvRepair-x64.exe in the C:\Program Files (x86)\PFU\ScanSnap\Driver\SsDrvRepair folder.
Red Slash Circle Troubleshooting
If you cannot scan and get a red circle with a slash through it on the Blue S Scansnap icon, try these:
Reboot your PC (especially if you've had your ScanSnap working before)
Perform "Scan for hardware changes" or "Refresh" from Device Manager. (*1) If the situation does not improve, perform step 2.
Update the ScanSnap driver. In the Device Manager window, right click on "ScanSnap S510", and from the pop-up menu, select [Update Driver]. If this does not improve the situation, perform step 3.
Disconnect and re-connect the AC cable and the AC adapter (Wait at least 5 seconds before turning on the power again.) If this does not improve the situation, perform step 4.
If an USB hub is used, directly connect ScanSnap to your PC. If this does not improve the situation, perform step 5.
If your PC has multiple USB ports, connect ScanSnap with another port. If this does not improve the situation, perform step 6.
Reboot your PC again..
If none of the above operations resolve the problem,
Uninstall and re-install ScanSnap Manager:
Make sure the personal computer and ScanSnap are powered on and connected properly. - In the "Device Manager" window, check if the ScanSnap is recognized as "unknown device".
If so,
Go to [Control Panel]>[System] and delete it. -
Close ScanSnap Manager - Go to [Control Panel], select [Add or Remove Programs], and uninstall ScanSnap Manager and ScanSnap Organizer.
Update:
B. Parkhurst reports success with this driver:
"I'm using a 3.06GHz dual core processor with 4.0GB RAM and Win 7 64bit OS. That may allow you to help others similarly configured. I moved the USB connection back to my hub and rebooted - ScanSoft stayed in working mode!
I did have to do the first part of the instructions a couple of times - without success.
I then followed the Red Circle/Slash directions through #6 before achieving success.
What a relief, since I have spent much of the day trying to resolve this issue. Thanks again for knowing and sharing your experience."
Thanks to Mr. Parkhurst for the feedback and additional tips.
