title: Python Bloomberg API ( 'DLL load failed' )
body: <p>My Python version is 2.7.3 and OS is Windows 7.</p>
  
  <p>I want to use the Bloomberg API libraries. Specifically, 'importing error blpapi' is my most problem.</p>
  
  <p>At <a href="http://www.bloomberglabs.com/api/libraries/" rel="nofollow">this site</a>,
  I've tried to run both Supported Release(v3.5.5) and Experimental Release(v3.5.3).
  But both are not work.</p>
  
  <p>Writing <code>import blpapi</code> in IDLE, 
  I keep getting an following error message:</p>
  
  <blockquote>
    <p><strong>Traceback (most recent call last):</strong></p>
    
    <p>File <code>&lt;pyshell#0&gt;</code>, line 1, in <code>&lt;module&gt;</code></p>
  
  <pre><code>import blpapi
  </code></pre>
    
    <p>File <code>C:\Python27\lib\site-packages\blpapi\__init__.py</code>, line 5, in <code>&lt;module&gt;</code></p>
  
  <pre><code>from .internals import CorrelationId
  </code></pre>
    
    <p>File <code>C:\Python27\lib\site-packages\blpapi\internals.py</code>, line 50, in <code>&lt;module&gt;</code></p>
  
  <pre><code>_internals = swig_import_helper()
  </code></pre>
    
    <p>File <code>C:\Python27\lib\site-packages\blpapi\internals.py</code>, line 46, in <code>swig_import_helper</code></p>
  
  <pre><code>_mod = imp.load_module('_internals', fp, pathname, description)
  </code></pre>
    
    <p><strong>ImportError:</strong> dll load failed specified module could not found</p>
  </blockquote>
  
  <p>How can I solve this problem?
  (I hope to import 'blpapi')</p>
