Error on Data Director: ConnectServerAndOpenDatabase Can not initialize automation server

I would like to record this error and the solution for my reference in future. We encounter this error when run the scheduler job by schedule, however if we run the scheduler job manually, it works perfectly.

This is the complete error on Data Director:
"PlusCFrontClient: ConnectServerAndOpenDatabase Can not initialize automation server\Program returned error"

Solution:
Choose the lowest notification level on User Account Control Setting (Windows)
