ERROR

After upgrading from License Manager 2021R1 to 2024R2, the license Manager would not start and gave an invalid host id error.  The MAC addresses detected by Ansys in the License Manager did not match all MAC addresses on the system, in particular, the one the license is issued to. 

Software & Version

License Manager 2024R2, License Manager 2021R1

*This example was taken from this version but is not necessarily limited to this version.

Description/Cause

This was on an VM hosted on Azure.  It's mac address was set to static.  A reboot was performed but did not resolve the issue.  After submitting this to Ansys on 8/21/24, they confirmed that this is a bug in this version.  They were not able to provide an ETA on a timeline for the fix at the time. 

Solution

1. Rehost the License and issue it to the DiskID on the machine, instead of a mac address.
