This feature is also good for my presentations in the future where no more warning dialogs for missing licenses will show up.
To store registration you can use a script step like this:
$r = MBS( "StoreRegistration"; Register::LicenseeName; Register::Component; Register::LicenseType; Register::ExpireMonth; Register::SerialNumber )
As registration details are stored in Filemaker preferences, you need to apply this for every Filemaker version you use. This should also work on a server.
