It runs with the permissions of defined Windows user, it can be configured and controlled by standard Windows tools (Services.msc console).
The service can be launched or stopped by the user (from command line or admin console), but this is only an instruction for action, the launch/stop itself is executed by the Windows system regardless if the user is logged in locally or remotely.
Although from the OS Windows point of view, these applications are not real services. But because these apps are launched by a real service PmRtManager, they run independently whether there is a logged user or not.
These apps run under the same user and with the same permissions as the real service. But these apps are not listed among OS Windows registered services, their configuration and management is fully under control of the PmRtManager. This is the basic procedure of launching PROMOTIC applications (and other programs) as OS Windows services.
Visible application (local or remote client) should be another normal PROMOTIC application (not a service) or Web client.
The old procedure of launching the PROMOTIC application as service by using the two utilities (Instsrv.exe and Srvany.exe) is no longer recommended. There are many disadvantages of the old procedure compared to the new one (getting the utilities, complex configuration), especially if the PROMOTIC application was stopped (crashed) the service still considered the application as correctly running (there was no WatchDog functionality). These utilities are contained in the Windows Resource Kit that is available for download at the Microsoft Web.
