You can pre-install an application that is associated with either users or workstations:
If the application is a non-MSI application (for example, an AOT application), NAL Workstation Helper uses the workstation's credentials to distribute the application.
If the application is an MSI application, NAL Workstation Helper uses the logged-in user's credentials. If you want it to use the workstation's credentials rather than require a user to be logged in (for example, to perform a lights-out distribution of the MSI application), you must enable the Distribute in Workstation Security Space if Workstation Associated option (Distribution Options tab > Options page).
