When launching a task in Automation Engine, the user who is logged in to Automation Engine Pilot will be used to resolve the SmartMark operator.
When launching the same task via the Launch Workflow command in Adobe® Illustrator®, the user specified in the Shuttle Preferences will be used. By default, this is user admin. So, this has to be changed to the user the operator is using to connect with the Automation Engine Pilot.
Go to Illustrator > Preferences > Esko > Shuttle Preferences.
Double click the server's name and specify the correct user.
