I have registered my own file extensions with the corresponding EXE files, so that I can open my protected workbooks from the Explorer. It generally worked fine. Now I made a new version with XLS Padlock, and when I double-click a file, it does not open the file, but only gives me the general start screen (Original Workbook, Choose Save File, Load A Recent Save). I am using XLS Padlock Version 2025.0. Was there a change for the current version? Can I get back to the desired behaviour?
