Are there any free software?

Answer 4

Bummer,
that was the only thing I could find on this problem
or reinstall and update your MS Windows
but it is even very doubtfull that that would help

an alternative might be that you start python

write a text file:

@echo off
cd\
cd c:\python27\python.exe

save as a .bat file
and associate the.py extentions to it

Hopefully that helps

Answer 5

You can just right-click on a .py file and tell it to open. Windows has no idea what to do with it, so you can then select the Python interpreter to run .py files.
