This error could happen with any user name - it is not limited to "AutomicUSER". For all user object names, the following should resolve this specific error.
When a user attempts to use the Utility, it does not complete its run and instead they receive the following error messages:

U0036192 Logon with user 'AutomicUSER/%' was not successful. Access denied.
No user object named AutomicUSER in Client 0.
