Monday, September 21, 2009 1:40 AMHi. I had been running Windows 7 Ultimate RC, since July. When I plugged in my scanner, it went and found the correct software (CanoScan Toolbox), and my scanner worked perfectly.
This weekend I installed Windows 7 Pro. When I plugged in the same scanner...nothing happened. So I installed the CanoScan toolbox, using the setup CD that came with the scanner. I didn't think much of it. Subsequently, I pushed a button on the scanner, and Windows Fax and Scan opened, and the scanner made a terrible noise.
When I open the CanoScan toolbox, and try to scan, it says "unable to select TWAIN source." I have tried the troubleshooter, downloaded the driver and the entire CanoScan program (for 64-bit Vista) from Canon's website, and tried many other fixes.
Any advice would be appreciated.
