установка Дженкинс на Windows Server

привет, ребята, не могли бы вы помочь мне с ошибкой ниже (не удается установить Дженкинс на Windows)

к вашему сведению: я установил jenkins из -> mirrors.jenkins.io/war я установил 1.454 в windows

после того, как я пытаюсь изменить свой номер порта: java -jar jenkins.war --httpport = 8800

я получаю следующую ошибку:
