This article deals with a scenario that is unique to SPSS in UCONN Anyware.
With SPSS 28, IBM introduced the IBM ID as a way to license an instance of SPSS. As of now, UCONN Anyware uses an ITS-managed license server to license SPSS. When you launch SPSS 28 for the first time in your Anyware session, you will see the screen below.
Choose Apply Existing License, and that will let you progress. You will not be asked that question again unless your UConn Anyware profile is reset.
