Common project settings are valid for all protection methods.
Common project settings can be mandatory and optional. For example, Application name, Application signature and Application filename settings are mandatory settings. You can not protect any application until these options are set. Most of other common project settings are optional. These options come with their default settings which you can further tweak to match your protection scenario and specific type of application.
Protection wizard can help you in setting project settings accordingly to your specific needs. Protection wizard can be started from Project menu or by clicking on Wizard button on main toolbar.
Use Project/Restore default settings menu option to reset all project settings to default values.
