When running PcVue as a service, this becomes a little more complicated with two additional components:

1. SV Core Daemon. Service responsible for managing PcVue components when run as a service.
2. SV Services. PcVue communicates with its own components, such as the Historical Data Server and Application Explorer, and with external components using DCOM technology. When running as a service, an additional component, SV Services, is required to manage this.

After selecting the user accounts in the console’s User accounts tab, open the Windows component services configuration dialog box. A shortcut is available in the Tools menu of the SV Core Management Console.

It is used to configure DCOM for the SV Services service, which cannot be done directly via the SV Core Management Console.

Expand the tree in the left-hand panel and select the DCOM Config node. Locate the SV Services object in the middle panel and right-click to select properties.

Select the Security tab and check Customize in Execution and activation permissions. Add the previously selected user. For this user, add only Local Execution and Local Activation. To open Application Explorer or Application Architect, do the same for the Windows session user concerned.

Repeat these steps for access authorizations. Close the Component Services Configuration dialog box and restart Windows.

But even with a runtime licence you should be able to open the user management part of the Application Explorer, if your account have the necessary priviledges.
