title: Microsoft Visual Studio 2015 Interactive window dicconnected - tried many solutions, can't work
body: <p>My issue is : I tried to run Python in the Visual Studio Express Desktop 2015, but the interactive window shows "disconnected". There is an error in the interactive window:</p>
  
  <pre><code>An internal error has occurred in the Interactive window.  Please restart Visual Studio. 
  </code></pre>
  
  <p>I can't type anything in the interactive window. Tried to restart it, nothing changed. </p>
  
  <p>I have already tried to uninstall and reinstall both Visual Studio and python tool. Error is still there. I googled this problem, someone suggested to install python interpreters also, by following this instruction:<a href="https://github.com/Microsoft/PTVS/wiki/PTVS-Installation" rel="nofollow">PTVS/wiki/PTVS-Installation</a> ; So I tried installing the Cpython and IronPython, but still get the same error... </p>
  
  <p>The software is run under windows system. My computer is 64 bit operation system. </p>
  
  <p>Any ideas? Thank you!</p>
