#42648 — Make python 3.3 the default one and not 2.7

Hi there, i installed python 2.7 (windows 32bit version) from http://www.enthought.com/products/epd_free.php and after that i installed official  3.3 version too. So now i got two python folders like this.. c:/Python27 and c:/Python33 . 
My problem is that when im trying to execute a .py file, the 2.7 version interpreter launces. In addition if i right click and select Edit with IDLE, again version 2.7 interpreter opens. How can i make python 3.3 the default one, as i need this cause i have PyQt4 installed there and so it does not work with 2.7 .
Thx in advance.

Check out the post at
http://stackoverflow.com/questions/4664646/how-to-change-default-python-version-on-windows-xp
.
Especially the part about changing the registry. The Python.File entry mentioned
there also has the information about the IDLE version to use.
Best,
Wolfgang

The [.CompiledFile\shell\open\command] sets the python version used
for running pre-compiled .pyc files.
Likewise, [.NoConFile\shell\open\command] sets it for .pyw files
(intended to be run not from a console window - hence the name of the
entry).
Usually, you will want to have all of them point to the same Python
version.

Best,
Wolfgang

That was one of the choices you were presented with during the install. 
  It defaults to making the newly installed one the default, but there 
was a checkbox or something.  (It's been years since I did a Windows 
install, so I don't really remember)

Anyway, if Wolfgang's link doesn't do it for you, consider re-installing 
3.3.  It should just go on top of the existing one, and the only change 
should be that it would then become the default one.

Not quite answering your question but are you aware of
