title: How to install the 64-bit version for Windows 10 of Graphviz 2.38
body: <p>The Graphviz download page has to links, one for a .msi file and another for a .zip</p>
  
  <p>when running the .msi, it looks that it's for 32 bits, since the default directory installation is "Program Files (x86)", which is where the 32-bit installations go.</p>
  
  <p>There are no instructions on what to do with the .zip    </p>
  
  <p>Has anyone installed the 64-bit version of Graphviz? Is there an installation script that installs the executables?  If so, where can I find it?<br>
  (I hope it exists, because I can't compile source code in my machine.)</p>
  
  <p>Many thanks in advance,</p>
  
  <p>Alex</p>
