Well, a bit more testing and I have proven myself incorrect.
I have an old linksys dongle for wifi on this pc as well as an ethernet port. Occasionally I still use it just to see if it works. The license error
did occur when I switched over to wifi. So, I ran the
fix for the first time on this install of 24H2. Does seem to have worked.
I rebooted. No license error after first reboot while still on ethernet. I then disabled ethernet and verified the wifi connection. MRX started with no license error. Then re-enabled ethernet and verified connection. MRX still did
not have license error. I am
assuming the fix is working. If I create conditions where the error occurs again I will make a note here. I know you folks do not really need my input.
