RoboTask forum

Can a Robotask task be run from a Command Line? If so what is the command required?

Of course. There is RTaskRun.exe utility for this purpose.
Command line is RTaskRun.exe <TaskID>
TaskId must be in hex or decimal format. For example:
RTaskRun.exe $3C46E896
Where "3C46E896" is a task ID (in hex) and the name of task file.
Remember that task must be registered in RoboTask.
Also you can create a shortcut on desktop for any task. Use menu Task | Create Shortcut on Desktop.

And can the tray icon be hidden?

Why do you want to hide tray icon? If icon is hidden how do you want to control RoboTask?

Where are the files that are created or which are the files that are used by 'Install as Service' and how does it differ from normal operation through robotask.exe?

When you launch "Install service", no new files will be created.

When the install as service shortcut is selected from the start menu, what changes to the existing files, is the only advantage that it runs regardless of who logs in and is the tray icon hidden?

When RoboTask works as service it can execute configured tasks even if no users are logged on. RoboTask service will be started together with Windows and you don't need to login to computer.

is there a command line parameter to stop and disable a task?

No. You can only start some task.

But you can stop or disable another task in this task. See actions Disable task and Stop Task

To create batch file for a task select the task and use menu Task->Create Batch File
