Have been trying to install an existing CanoScan 5200f scanner on a new windows7 PC. Windows did not recognise it for automatic acceptance. D.loaded driver from Canon site, and installed it. It has been accepted and is being shown as working correctly. When I try to use it I get 'There is no application for this event'. Anyone had experience of this problem?.
The error is literal. It means you don't have any of the software installed that your scanner output could be automatically sent to when you use the scanner buttons. I don't know which image editing app came with your scanner but the one I got with mine is not Win7 compatible and had to be removed since there was no update for it from the sofware vendor. You can download and install a Win7 version of Canoscan Toolbox and use that instead. It can redirect the scans to whatever software you want, or to a file. You should also be able to "Acquire" scans directly into any other imaging software which has that option.
