+ <paragraph role="paragraph" id="par_id721623369245475">To run Python scripts from a separate process, you need to start %PRODUCTNAME with a few additional options that specify the hostname and port through which the external process will communicate with the %PRODUCTNAME component process.</paragraph>
+ <paragraph role="paragraph" id="par_id221623369584132">Open the your operating system's command prompt, navigate to the program folder of your %PRODUCTNAME installation directory and type:</paragraph>
