If you are using a plist file license, it will not present the mailing list/registration window.
However looking at the code I see it will still show a "Welcome to Hype" window, basically this page:
https://tumult.com/hype/welcome/4.0/welcome.html
If you don't want to show that on a clean install, you would use this defaults command:
defaults write com.tumult.Hype4 showWelcomeToHypeOnLaunch -bool NO
