Python 2.7 and 3.5 Windows Install
<p>I have both 2.7 and the latest 3.5 Anaconda Python version installed. </p>

<p>2.7 is my old one and I just installed the 3.5 one today. The first time when I installed 3.5 today I downloaded the .exe from their website. I used Pycharm IDE so when I went in there to change the interpreter i got the following error message:</p>

<pre><code>Cannot set up a python SDK at c:\user\asd\Anaconda\...\python.exe
This SDK is invalid.
</code></pre>

<p>I tried to add it to my path but that didn't solve my problem.</p>

<p>The second approach i tried is to uninstall it and install it via conda as a second environment.</p>

<pre><code>conda create -n py35 python=3.5 anaconda
activate py35
</code></pre>

<p>All this worked and when I successfully activated it I typed python and this error came up:</p>

<pre><code>Fatal Python Error: Py_Initializer: unable to load the file system codec
File "C:\User\asd\Anaconda\Lib\encodings\__init__.py", line 123
    raise CodecRegistryError,\

SyntaxError: Invalid syntax

<p>I am totally confused on what the problem is and why i cant seem to run python3.5 with python 2.7 also installed.</p>

<p>thanks</p>
