If the drive-letter is shown in My Computer for the Canon camera, then
right-click the drive, and choose Properties. Click the Autoplay tab, and
choose the desired application there.
Alternately, start Registry Editor (regedit.exe) and navigate to the
following branch:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\AutoplayHandlers]
Export the branch to a REG file, using the File/Export menu option.
Then, delete the sub-key named "UserChosenExecuteHandlers"
Close Regedit.exe
Note that this resets the Autoplay preferences for _all_ the removable
drives in the system. You may need to reconfigure them again.

I did a bonehead thing when I was troubleshooting a problem recently, w/my
new Canon SD550 camera connecting to the Canon software in Windows. When I
first connected the camera, I got the usual dialog box of all the various
programs on my machine that could connect to the camera and download
pictures
(Adobe Photoshop Elements, ACDSee, the Canon CameraWindow, etc.).
The bonehead part comes in when I checked the "Always perform this action"
w/the "Canon CameraWindow" selected. Now when I connect the camera, the
Canon
CameraWindow always starts, never giving me a choice of which program I
actually want to use. D'oh! Yes, I know it's doing exactly what it's
supposed
to do. Problem is, I want the dialog box of choices back, and I don't know
how to get it.
W/a simple file association, I know you can go into My Computer>Tools>Folder
Options>File Types tab, and scroll down until you find the file type you
want
to change the association to. Trouble is, the camera is of course a hardware
device, and I have no idea where to look for the magic place to undo what I
did. It is *not* in the File Types list.
I've hunted thru the Registry, scoured the KB, and have simply run out of
ideas. Can anyone tell me how to undo a device association to a particular
program?
