Heya, I'm not sure I understand, this add-on doesn't have anything to do with opening .blend files from your file system. You can set the blender version associated with .blend files in Blender's preferences. Also keep in mind that files can have workspaces in them, which can have add-on filtering enabled, which might be disabling this add-on.

Version 1.6.13, the plugin does not work properly when double-clicking to open a .blend file. It works normally when opening Blender software and then dragging the file in.
