It means that this call is failing. You need to find the reason for it and eliminate it. Good luck! Read up in the closed issues for troubleshooting. Start here https://github.com/murrayju/CreateProcessAsUser/issues/18 and follow the links.

Most likely a permissions problem, are you running the service as the System account?

You could also try calling the win32 GetLastError() for more clues.

@hedbisker do you need any more help with this?

@AndrewSav No, thank you
