This issue is caused by various things, but the most common are:
The connection to the LED device wasn't successful. Before modifying other parameters, test the connection and make sure that it's successful.
Permissions: Run the application as Administrator. If those parameters need saving to a FILE on the system partition and you launch it as a regular user, then you will receive the above error.
Note: I don't think that Firewall needs to be configured since we're talking about local connections, but add the LED Control Center to the Exclusion list just to be sure everything works normally.
Getting a message "Failed to set Parameters".
