Hello, I have an issue with my CanoScan Lide 500F scanner. I have viewed a similar question that was posted in 2008 and followed the advice given there, to no avail. I have used this scanner with this computer (a Fujitsu FMV-Biblo NF/G50 running Windows 7) successfully (the last time I used it was in May this year). However today when I tried to use it, the ScanGear Starter wouldn't open when I double clicked on it. I have tried uninstalling the driver and then re-downloading (ScanGear CS 11.220a) the latest driver. I have also tried downloading and installing the Canon Toolbox (version 220.127.116.11). I still can't get the scanner to work. When I go to the control panel and find the scanner, the computer has registered that it's connected, but says it needs an appropriate WIA driver to run it. Does anyone have any suggestions?
