title: PyCharm: Py_Initialize: can't initialize sys standard streams
body: <p>I'm trying to use PyCharm IDE but none of my programs compile even simple Hello World. PyCharm gives this error: </p>
  
  <pre class="lang-none prettyprint-override"><code>Fatal Python error: Py_Initialize: can't initialize sys standard streams
  Traceback (most recent call last):

  <p>I'm not able to find the solution for it and also referred the link <a href="https://stackoverflow.com/questions/7111025/pydev-fatal-error-python32-lib-io-py-line-60-in-module">PyDev: Fatal error Python32\lib\io.py, line 60, in &lt;module&gt;</a> but there is no solution there.</p>
  
  <p>Python 3.4 is installed on my Win 7 OS system.</p>
