The License Manager installer not only creates the Service, but sets it to start automatically. To do this manually:
1. Open an administrative CMD line window:
Open Command Prompt as Administrator (Enter CMD in the Search box and simultaneously click Ctrl+Shift+Enter. For the Windows Command Processor click Allow).
At the command line, enter CD C:\ExtendSimFloatingLicenseServer (assuming that is the directory where the License Manager was installed) and press the Enter key.
At the new command line, enter rlm -install_service -dlog logfile -service_name extendsimlicserver. Press Enter.
Close the window.
2. Go to Computer Management on the License Server.
Go to the Services and Applications/Services section.
Select ExtendSimLicServer in the list of Services and Start the Service.
Right-click ExtendSimLicServer to access its Properties and set the startup type to Automatic.
