How to use runner.py in sumo via command line and solving its common error(permission denied)

When I try to use the runner.py example via the command line, I encounter the following error:

C:\Program Files (x86)\Eclipse\Sumo\doc\tutorial\traci_tls>runner.py Traceback (most recent call last): File "C:\Program Files (x86)\Eclipse\Sumo\doc\tutorial\traci_tls\runner.py", line 122, in generate_routefile() File "C:\Program Files (x86)\Eclipse\Sumo\doc\tutorial\traci_tls\runner.py", line 47, in generate_routefile with open("data/cross.rou.xml", "w") as routes: PermissionError: [Errno 13] Permission denied: 'data/cross.rou.xml'

Who knows how to solve this error? Regards, Ali
