cocos2d-x3.0rc0 problem with setup.py

Error infomation :
C:\Users\Administrator>F:\cocos2d-x-3.0rc0\setup.py
File “F:\cocos2d-x-3.0rc0\setup.py”, line 114
print ‘Warning: Could not add “%s” into registry’ % key

my system is win7 X64,can x64 use this script ?
I checked the setup.py ,I saw some content before line 114:

modify registry table to add an environment variable on windows

def _set_environment_variable_win32(self, key, value):

Thank you !

not only setup.py
cocos.py have error too.
Is this tool only support win32 now ?

finally I found the reason.
it is The edition of Python .
my Python edition is too late,so the print turn to a function ,the print content must have a pair of brackets .

it would be good if the python scripts could be made to work with python 3.

All script used in cocos2d-x only supports python v2.7.5. It doesn’t support python 3.

It will bring much work to support both python 2.7.5 and python 3.
May be we will make it available when all tools are stable.

thanks
