I am using a Windows Vista Home Premium 32-bit desktop with Canon PIXMA MP600. Suddenly something went wrong with this system. I am now no more able to change the program that handle scan events. Whenever i try to do the same, it ends up with the following error message:
"Event Registration Failed
The attempt to change the register event handler failed. Please make sure the device is turned on and connected properly."
This error pop up use to have OK button which on clicked dont do anything. Its parent process is ImagingDevices.exe running on my system. As per troubleshooting i already tried re-installing drivers, updating drivers but that doesn't seems to be working. Later i also tried contacting Canon Support for help but they said the problem is with Vista and not with their product.
Thats really very annoying. Is there anyone else facing this problem or just me? Any working solution? Many Thanks.
