title: Error in Converting PDF to PostScript with GhostScript, Access is denied Unable to open command line file _.at
body: <p>I installed <code>ghostscript</code> and updated the appropriate <code>path variables</code> ... however, I'm getting an error when I try to execute this command:</p>
  
  <pre><code>C:\PROGRA~1\gs\gs8.64\lib&gt;pdf2ps mydocument.pdf mydocument.ps
  Access is denied.
  Unable to open command line file _.at
  </code></pre>
  
  <p>Is this the right command? Did I miss some configuration or path setting? Otherwise, is there a sane method of doing this conversion?</p>
