Hi, i'm using ArcGIS Desktop 10.8.1 for a specialization of five courses named "Geographic Information Systems (GIS) specialization" offered by UCDavis, California.
In the instructions (i attached a screen of them) there is a specification about an 1-year ArcGIS Desktop license that have been provided by Esri.
After receiving the license via mail on October 10th 2021 (screen attached) and installing the software, as i checked in ArcGIS Administrator it says me that the expiring date of my license is on December 29th 2021 , while it should be around October 10th 2022 (Screen attached).
That may be the expiry date for the university's license... It will be updated when it is renewed.
If you have concerns, contact the administrator at your university or the course instructor if you don't know who it is
