Programs (Applications) not in list to be chosen as "defaults"

I am trying to set Quicken as my default PFM application (so that it will automatically open QFX file types), but even though the program is loaded and working it is not presented in the list of "applications" to be selected and used as a "default" application?? When I search for it, Windows does not find the application.

Also, I've set Internet Explorer as my "default browser" and chosen the option to open all associated file types, but whenever I click a URL or link embedded in any e-mail or document, I am asked what application I want to use to open it. I select "Always use this app" every time, but the next time I click on a link/URL I get the same annoying pop-up. How do I fix this??

Hi, firstly, have you tried using the original Control Panel 'Default Apps'? I had a problem where using the new settings interface did not fully associate all protocols and extensions with my browser.

Secondly, you might like to look at a freeware program: 'Default Programs Editor' if you have a particular need or problem.
Hope that helps.
