> No,I cant ! That problem is during that I run the talker & listener demo. Sorry for being unclear. Can you please try to run the executable directly: ``` /Lib/demo_nodes_py/talker.exe ``` Both - this command as well as the `ros2 run` invocation - work for me using the released Beta 2 archive. --- [Visit Topic](https://discourse.ros.org/t/failed-to-load-entry-point-for-command-ros2/2363/5) or reply to this email to respond.
