Duplicate Port issue after upgrading from Change Auditor v6.6 to v6.9.5
After upgrading the coordinator from Change Auditor 6.6 to 6.9.5 and using the same port settings the coordinator will not start indicating the port is already in use.
Earlier versions of Change Auditor did not thoroughly check for port conflicts and would start even if custom port settings were using the same port. Typically the Legacy agent service CA4xcompat.exe would not initialize if ports were the same, however the coordinator would start.
Edit the Coordinator configuration by right clicking on the coordinator systray icon.
Ensure all the ports have different values (Default 0)
