title: numpy python 3.4.1 installation: Python 3.4 not found in registry
body: <p>I have two python versions on my computer 2.7 and 3.4.1 . I have tried to install numpy by pip3.4 which resulted with <em>vcvarsall.bat</em> not found which i am pretty sure it is included in system path. Then i gave up downloaded numpy binary <a href="http://sourceforge.net/projects/numpy/files/NumPy/1.8.1/" rel="nofollow">numpy-1.8.1-win32-superpack-python3.4.exe</a>. And during the installation it tells me that numpy cannot find python 3.4 in the registry which i see that it is there also.</p>
