Boost installation failed: The system cannot find the path specified
<p>I'm unable to install the latest version of <code>Boost</code>, i.e. <code>1.61</code>. What I did was to run "<code>bootstrap.bat</code>" from the boost root folder in <code>Windows 7</code> prompt command, but error message says:</p>

<blockquote>
  <p>Building Boost.Build engine The system cannot find the path specified.</p>
  
  <p>Failed to build Boost.Build engine. Please consult bootstrap.log for
  further diagnostics.</p>
</blockquote>

<p>Any help appreciated!</p>
