CreateProcessAsUser — Ошибка 1305

У меня есть служба, и мне нужно запустить приложение графического интерфейса пользователя с привилегиями текущего пользователя из этой службы. Это мой код, и он всегда возвращает GetLastError с функцией 1305 CreateProcessAsUser. Как я могу это исправить или, возможно, мой код неверен, и вы можете посоветовать мне что-нибудь полезное. Спасибо.
