Solved "Select an app..." opens even after default is set

Working fine 2 days ago. Today when I click on a jpg file I get the "Select an app..." to open which is already shown as set to Infranview. I click to make it "always" again but the "Select an app..."still pops up every time. Reset all assocations which did not help. Used the jpg.reg file on the registry as found here which did not help. Tried uninstalling Windows Photo app and that did nothing as well.

Windows version 22h2 buil 22621.1265

Hi and welcome to the forum.
File associations have changed. I would avoid using the .reg files as one did in Winx.
How do you have it set up here?

I already tried the above multiple times; does not work. Note that also, when using Windows Explorer the default Infranview is recognized and opens without a dialog. But in other file browsers, it does not work.

I discovered the problem was with Freecommander file manager.

Hi James. Can you please be more specific? In FreeCommander have you gone to Tools > Settings > Programs and defined Infranview for the jpg extension?
