Upgrade to 2021 R1, and new version of programs get license error.
We are in the process of updating our versions of ANSYS on our lab computers from 2019 R3 to 2021 R1. Our license server manager updated the license server to 2021 R1, and we’ve done a few test installs of the client 2021 R1 version, which have gone fine. When most of the individual ANSYS models are launched though, they get an error saying no valid license detected (attached log from trying to run Mechanical 2021). We’ve tried version 2021 R1 on computers with no previous ANSYS installations as well as ones that still have 2019 R3 installed. On the machines with 2019 R3, they can still access all of their modules without issue -connecting to the same license server on the same ports. In the attached picture the screenshot on the left is version 2019 R3 and the one on the right is 2021 R1, showing the differences just from the Workbench as well. Any help would be much appreciated
