Install SITL on Windows

I’ve got a problem when I install SITL on windows. I’m following the tutorial :
Just after step “Download and make ArduPilot”, I try to run, but this file doesn’t exist, so I don’t where this file is and how to execute it?
Can someone help me to fix this issues?
Best regards

Sorry guys, I just discover my mistake.
When you install Cygwin, yo have to clone the code of ardupilot from Git directly in the directory “Cygwin/home/PC_name/”
