SOLIDWORKS 2024 Activation Support - Serial Number Not Eligible

My name is Mustapha Ben Haj Naser, and I am a student at the University of Rostock. I received the serial number for SOLIDWORKS from my university. After downloading and installing SOLIDWORKS, I encountered a problem during activation, as I received the following error message: "Serial number not entitled to SOLIDWORKS 2024." I have confirmed with the university that the provided serial number is correct. Could you please advise me on how to solve this issue?
