Thanks for looking into this and notifying us also. I heard some vague
reports but nothing concrete like this.

I know kns3 isn't using this support class to migrate it's registry of
what's been installed to the new locations it uses. Just curious, what
"support class" are you referring to here?
I know kanagram/khangman also don't use this, but that's probably not as
important, since they don't have many settings anyway.
