I am trying to set the default programs for my Epson V200 scanner buttons
using the Scanners and Cameras Control panel applet. When I choose the
program and click OK I get the following error message:

Event registration failed: The attempt to change the registered event
handler failed. Please make sure the device is turned on and connected
properly.

When I press any of the buttons it brings up a dialog that allows me to
choose a program. The scanner functions normally once the application is
running.

Any ideas why it won't let me change the registered event handlers?
 
This turned out to be permissions issue. I had to take ownership of the
applicable Registry keys as an Administrator. I was then able to set the
button assignments as an Administrator.

I got an email response from Epson regarding this problem and their only
suggestion was to reinstall the driver, which I had already done.
