Symphonic orchestra library not licensed

@jamozart1: That sounds all strange.
Could you please post a screenshot of the eLicenser Control Center window?
Also, please start Dorico, open that particular SATB project and then on the main menu choose Help > Create Diagnostic Report.
That will create a zip file on your desktop, please send that one to u dot stoermer at steinberg dot de.
From the contained log files I can get a better overview of what is actually installed and what the program is doing.
I will then give more advice.
