Suddenly all Adobe icons on my desktop changed to Canon printer/scanner icon. Opening the files results in a window which has to do with my printer. There must be some sort of pathway impediment. Help! Using Reader X, Windows 7. I can view PDF's by opening the Adobe Reader program but that's a pain.
Uninstall and reinstall should fix the associations; unfortunately a repair does not. Alternately, you can right click on a file and use Open With to choose Reader as the default program again, but it will give you a funny-looking icon.
