title: Call .exe from batch file with variable path containing spaces
body: <p>I want to launch a windows executable from a batch file where the path to the executable is stored in a variable.</p>
  
  <pre class="lang-sh prettyprint-override"><code>@echo off
  
  set qtpath=C:\Program Files\Qt\5.7\mingw53_32\bin
  set execpath=%qtpath%\windeployqt.exe
  
  echo %execpath%
  
  %execpath% --someparams
  </code></pre>
  
  <p>Unfortunately executing my script throws an error:</p>
  
  <pre><code>'C:\Program' is not recognized as an internal or external command, operable program or batch file.
  </code></pre>
  
  <p>Looks like somehow the string gets terminated at the space in <code>Program Files</code>.</p>
