stop fireworks

Hi; I don't have Fireworks, Photoshop does what I need. Every time I try to
open a graphic file. .jpg--etc Fireworks starts and can't find
Fireworks(because I don't have it) I have to shut that down and try again. How
do I stop Fireworks from trying to launch???? I have set my Preferences to
select Photoshop as my graphics editor. This is a pain. HELP

this has to do with your file association table on your pc.
to change it, open a folder, go to Tools > Folder Options

Select the File Types tab, will take a few seconds to generate, find the
appropriate file types ie .jpg .png and edit them to use photoshop or whatever
else you want.
