@David-Healey No, because this is about persisting the file to the user's disk.
Although as I said earlier, I think the final best answer is to display the license directly in the plugin somewhere.
Then nobody could ever accuse the developer of not making the license easily available.
Website goes down - no problem
User moves the plugin to another machine - no problem
User wipes/moves/modifies their AppData folder - no problem
If the license is in the plugin itself, it can't be accidentally moved, deleted or overwritten, and it can't become unavailable because of server outage.
Probably going this route now...
