Hello and welcome to our forums,
What you want to achieve is actually a default setting of Advanced Installer. "Pre-Install" prerequisites are displayed in the Boostrapper "PrerequisiteDlg" in case they are not installed on the target machine, otherwise the dialog will not be displayed.
Also, please make sure that "Always install prerequisite" option is not ticked. To check this, go to "Prerequisites" page from the "Requirements" group, click on your "Pre-install" prerequisite, go to "Install Conditions". If this is not ticked, please make sure that you do not have an "Install Condition" that always evaluates as false, otherwise your prerequisite will always install.
Regards,
Catalin
