A process is running on a Solobot, and it fails with the two error messages logged as below:

"Process failed to Start in non-interactive mode because of the User is not registered as a Batch-User"

Immediately followed by:

 ARMRJ03 Internal error while attempting to start process 'ProcessName'. Process did not start.


These errors are usually caused by invalid User Credentials specified as login credentials to a specific process.

To resolve this, navigate from the Control Desk to the Processes tab, locate the specific process right-click Edit Process Properties > Credentials and uncheck the Override Credentials option. 

Alternatively, make sure that the credentials specified are correct.
