Thank you for the fast response!
Unfortuantely, we are trying to use Group Manage System Account, as far as I know, Load user profile is not an option, because this type of account does not support user profile. Anyway if i try to do so, VisualCron give this error:
And task error output is : Could not start process as another user. The username, passwor or domain was incorrect!
Greetings,
