I don't understand what's going on here. I've tried Filetypesman - x64 , to try to change the association , but nothing works, it continues to revert back to Icon Developer as the default program for opening dll files. This is in Windows 11. I really don't know how else to explain this , so I've included a screen capture to show what I'm talking about. Anybody out there know anything about this and whether it can be corrected -- or not ? Thank you.
