    Impossible to install. Various directions tell me to run one or another .exe, none of which I can find. Tell me to install prerequisites, then tell me one-click-does-all. Finally got a Leo shortcut on my desktop (target: C:\Python34\pythonw.exe "C:\Program Files (x86)\Leo-5.4\launchLeo.py", start In: "C:\Program Files (x86)\Leo-5.4\leo"). Double-click and the mouse icon spins briefly; nothing after that. Turns out that LEO assume a .py extension is associated with python (in my case it is not). So I finally got LEO up. It was touted as an IDE. After wading thru LEO in 10 minutes, text tutorials, videos (how ... slowly ... can ... I... read ... the ... words ... on ... the .., screen ... before ... I ... SCREAM.) I still have no idea how to enter and run a python program. Oh well.
