ROS2 windows installation failure

edit

I am following the guide: https://docs.ros.org/en/foxy/Installa... and every step is successful, except for this one:

Try some examples

ros2 run demo_nodes_cpp talker

The program does not say anything and end up silently after 1 second.

ros2 run demo_nodes_py listener Error goes like this: RuntimeError: Failed to initialize init_options: failed to load shared library 'C:\dev\ros2_foxy\bin/rmw_fastrtps_cpp.dll' due to LoadLibrary error: 126, at C:\ci\ws\src\ros2\rcutils\src\shared_library.c:88, at C:\ci\ws\src\ros2\rmw_implementation\rmw_implementation\src\functions.cpp:84, at C:\ci\ws\src\ros2\rcl\rcl\src\rcl\init_options.c:61
