On Microsoft Windows you will need to install and run the RLM License server as a Windows service process. A service process will start automatically when the computer boots up and will remain running as long as the computer is up. Installing RLM as a service is done at the command prompt. Once installed as a service it remains installed until it is deleted as a service. Deleting the service removes it from the Windows service database and does not delete the rlm.exe or associated file(s).
