title: VS 2015 Error:The WiX Toolset v4 build tools must be installed to build this project
body: <p>I have <strong>VS 2015</strong> and I have installed <strong>Wix v3.10</strong> but when I try to build the setup project it shows me this error:</p>
  
  <blockquote>
    <p>The WiX Toolset v4 build tools must be installed to build this project.</p>
  </blockquote>
  
  <p>I don't want to install wix v4 because it's not stable yet.</p>
  
  <p>How I can get rid of this error?</p>
