Problem opening AR4.py

So if i download the AR4 Version 2.0 (Source)

hen go to my Desktop and double click on the ( AR4.py ) File nothing happens CMD open for a split second then nothing

i have these installed...

(This is a fresh install)

And i have these installed through the CMD Prompt

I have tried opening the file (AR4.py) with no modification and it still wont open.

and i have also tried editing some code saving and then tried opening and it still wont open have i done something wrong?

Failing that is there away to de-compile the Working AR4.exe to edit code and then re-compile it? i cant find any documentation on Compiling either
