Yes, I have IDLE installed, and Launcher is installed as well. I can open up IDLE from the shortcut, however I am not able to access it within "Open With" or "Default Programs" or "Change" (within Properties). I _can_ open up the file only if I open up IDLE first then click "File" and then "Open" of the .py file in question. But the process of doing that compared to just double-clicking the IDLE-associated .py file is enormous and a workaround I'm trying to avoid. 

I've done steps 1-4 on a clean installation however there is one thing missing: the Python Launcher. It does not appear in the list of programs to choose. I tried everything up to and including idle.bat. But I'm not going to use idle.bat, that is a workaround I'm also trying to avoid. I just want a correct installation. I think it has something to do with my OS preventing the Python Installer from tinkering with the "Open With" options. 

The original shortcut for a clean installation for me is the python run command in the command-prompt. I need to able to see the code in IDLE when I double click on a .py file. 

Thank you for your help.
