If you are running the application through the Windows Service Console, select the installed application in the Service Console (make sure it is running), then on the 2nd row of the toolbar, click the Advanced>Show or add license... button
Have you checked this How To?
Hi Willem, Hope you are well!!
Im not sure that functionality exists in 5.21? The usual system administration pages are there, Active sessions, Run time instances, run time statistics and scheduled events. Cant see anything for license info.
Afternoon, The server id can be found on the server console (Windows) by clicking show / add license. Then when the license pop up screen appears clicking 'Reactivate License'.
