Is there any way to add (or even delete) an application from the list of options that appears when you want to set a default to a different program?
My photo downloads are set to open with a program that is out of date. The up-to-date program, which I have been using for a while now, does not appear in any list of default options. I haven't been able to find a way to add it and so select a new default, either in the download options drop-down or in Settings/Defaults. If I "Browse" for the correct application, it is in the correct file location, but I see no way to select it either as a new default or even as a single-use option for the current download.
I'm using Windows 10 on a PC. The particular programs involved are Adobe Lightroom CC (the old one) and Adobe Lightroom Classic CC (the new one). I have reasons not to just delete the old program.
In any case, the question is actually generic: How does one "edit" the default-options-lists? (Googling this question has not been helpful.)
Thanks for any suggestions.
