title: Python installer for Windows: disable path length limit option not available
body: <p>According to <a href="https://aatayyab.wordpress.com/2016/12/25/install-programming-language-python-for-windows-10-64-bit/" rel="noreferrer">this article</a>, when you install Python 3.6 on Windows, the last screen of the installer looks like this: </p>

  <p>I recently had some trouble with long pathnames in Windows, so I was looking for the "Disable path length limit" option in this screen. I installed Python 3.7 on Windows 10, but the "Disable path length limit" option was not visible. 
  The <a href="https://docs.python.org/3.7/using/windows.html?highlight=path%20length%20limit" rel="noreferrer">Python documentation</a> says nothing about this option. </p>
  
  <p>How can I get this option to appear? Or is it no longer an option in v3.7? </p>
