UEFI — ImageLoad не работает — ошибка = не найдено

Я пытаюсь загрузить приложение MyHelloWorld из другого приложения. Но получить ошибку, не найденную из функции ImageLoad, хотя путь в порядке.

MyHelloWorld.efi находится по адресу «fsnt0:>project1>MyHelloWorld.efi».

Что мне не хватает, что он не находит приложение?

Приложение работает на UDK2010 - NT32 (Developer Kit)
