Some applications (or some features in the application) require high user's privileges. Windows NT systems support (basically) two types of user accounts: administrator and limited.
Use checkup of administrator privileges - serves to check if the user's account under which the protected module is executed has administrator privileges or not. If the account is limited, then the protected application will not be started. Note: for Windows ME, Windows 98 and Windows 95 it always returns true (meaning that the user has already got high privileges).
Show message before termination - if you want to inform the user that they should increase their user privileges, enable this option. To edit the message, press "Design Message" button. If this option is disabled, the execution of the module will be terminated without notification.
