I have installed my top favourite graphics editor, Paintshop Pro 5, in my new laptop running Windows 10 and it appears in the list of All Apps in the Start list. But when I try to make it the default program for opening jpegs, etc., it is not listed, and when I right-click a jpeg in Files Explorer and click "Open with", Paintshop Pro is not listed as an option. Yet I can open jpeg files from Paintshop Pro itself. How can I get Windows to recognise Paintshop Pro as a program that can open jpegs and other graphics files so that I can make it the default program for graphics?
