title: Microsoft Visual C++ 9.0 is required
body: <p>When I want to install packages, including Jupyter, I get the error that Microsoft Visual C++ 9.0 is required. I get the same error with Pip and pre-compiled binaries on UC website.</p>
  <p>I have Visual Studio 17 express installed and I have manually added the path of <code>vcvarsall</code> to my environment.</p>
  <p>I also saw solution to update the <code>VS###COMMONTOOLS</code>, however <code>VS###COMMONTOOLS</code> variable doesn't exist.</p>
  <p>I am using Windows Server 2012.</p>
  <p>How can I proceed?</p>
