We have version 3.x and we upgraded from monthly to perpetual license by replacing the license key in the Server.license file but after the service was restarted we got the following error code:
ERROR: License key is not valid or license file does not exist and running as a service (exiting)
I see in the docs that the cause is the result of a perpetual AddOn license key being used without a valid Wowza perpetual license in place. We do not have any AddOns at the moment so I’m not sure how to resolve.
