title: How to create a 64-bit python 2.7 environment in anaconda?
body: <p>I installed a python 3 anaconda file in windows and it's working fine.For a new project ,I am required to use python 2. So, according to the instructions given at official <a href="http://conda.pydata.org/docs/py2or3.html" rel="nofollow noreferrer">anaconda blog</a> ,I created a new python 2 environment using the following command.</p>
  
  <pre><code>conda create -n py27 python=2.7 anaconda
  </code></pre>
  
  <p>But when I am trying to import numpy</p>
  
  <pre><code> import numpy as np
  </code></pre>
  
  <p>Following error is raised.</p>
  
  <blockquote>
    <p>ImportError: DLL load failed: %1 is not a valid Win32 application.</p>
  </blockquote>
  
  <p>According to online post this error is raised because I am using a 64-bit system.So,From the suggestion of this <a href="https://stackoverflow.com/questions/33709391/using-multiple-python-engines-32bit-64bit-and-2-7-3-5">stackoverflow post</a> ,I used </p>
  
  <pre><code>set CONDA_FORCE_32BIT=
  conda create -n py27_32 python=2.7
  </code></pre>
  
  <p>and created a new environment and activated it.But, I am getting the same error as above when I imported Numpy.</p>
  
  <blockquote>
    <p>ImportError: DLL load failed: %1 is not a valid Win32 application.</p>
  </blockquote>
  
  <p>So,64-bit python 2.7 is not installed.
  Is there a way to install two anaconda files i.e anaconda python 2.7 64-bit version and anaconda python 3.5 64-bit version in the same windows computer?
  If so,How to use different versions in jupyter notebook?
   Is it possible to install 64-bit python 2.7 environment?</p>
  
  <p>MY System Details:
  os : windows 7
  processor : i3 intel processor.</p>
