If this option is selected, you can specify the account under which the application installer will be run. You can specify the user account if Network Agent has not been installed on the devices for which the task is assigned.
You can specify multiple user accounts if, for example, none of them have all the required rights on all devices for which this task is assigned. In this case, all accounts that have been added are used for running the task, in consecutive order, top-down.
If no accounts have been added, the task will be run under the account under which the Administration Server service is running.
