I'm trying to load MyHelloWorld application from another application. But get error not found from the ImageLoad function, although path is OK.
MyHelloWorld.efi is at "fsnt0:>project1>MyHelloWorld.efi".
What am I missing that it doesn't find the Application?
The application is running on UDK2010 - NT32 (Developer Kit)
