If you are using Parental Control, you do not need to set a new password. Your existing Parental Control password is already protecting your program settings.
Press the F5 key to open Advanced Setup.
Click User Interface, expand Access Setup, and then click Set.
In the Password setup window, type your password in the New password and Confirm password fields and click OK.
Click OK to save your changes. You will now be prompted to type this password each time you attempt to modify program settings.
