title: Anaconda install package without administrator rights
body: <p>I have a python installation in a directory where I don't have admin rights or write permission. I am using Python 3.6.5 and conda 4.5.4 on windows 7.</p>
  
  <p>When  run <code>conda install -c conda-forge python-fmask</code> I get the following error message:</p>
  
  <pre><code>Preparing transaction: done
  Verifying transaction: done
  Executing transaction: failed
  ERROR conda.core.link:_execute(502): An error occurred while uninstalling package 'defaults::pytables-3.4.3-py36he6f6034_1'.
  
  PermissionError(13, 'Access denied')
  </code></pre>
  
  <p>The folders <code>conda-meta</code> and <code>pkgs</code> are located in a directory where I have write permission. There are hardlinks to these folders in the Anaconda installation directories. In which directories does conda need permissions in order to install packages?</p>
