It doesn't have to be pretty. Just tell the user to copy the data.tar.gz file and reboot. And in my opinion, the pc side should not contain any executables/scripts since users may not want to run some random exe even if it's to properly copy the tar.gz
Oh, and in case you haven't figured it out already, the payload still works. Aka, installing the custom key without replacing any files.
