When you try UpdateShield with an evaluation key, it is assigned with the trial system ID. You should use the trial UpdateShield for evaluation purposes only and should NOT distribute your software integrated by the trial UpdateShield. Your software could be unstable when it interferes with another of the same trial system.
When you acquire the licensed UpdateShield, it will be assigned with a unique Key ID for your unique system.
