title: VLFeat - How to fix "Warning: Name is nonexistent or not a directory"?
body: <p>I downloaded the <a href="http://www.vlfeat.org/download.html">VLFeat</a> lib from its <code>git</code> repository! I followed the instruction in the <a href="http://www.vlfeat.org/download.html">installation</a> page. But when I ran the <code>vl_setup</code> command I got this warning:</p>
  
  <p><code>Warning: Name is nonexistent or not a directory: ..\Adv. 3D
  Computer Vision\vlfeat\toolbox\mex\mexw32</code></p>
  
  <p>So follow some steps mentioned in MathWorks website, like <a href="http://www.mathworks.com/matlabcentral/answers/42690-warning-name-is-nonexistent-or-not-a-directory">1</a>,<a href="http://www.mathworks.com/matlabcentral/newsreader/view_thread/245866">2</a>,<a href="http://itsallmacademic.com/2012/06/16/matlab-warning-name-is-nonexistent-or-not-a-directory/">3</a> but the problem didn't solve. I trace the <code>vl_setup.m</code> file and according to the error statement it can not find the <code>mexw32</code> folder. but there wasn't any folder like that when I downloaded that lib. </p>
