title: Adding porter stemmer module to drupal
body: <p>I am new to drupal but was able to install acquia-drupal 7 with the microsoft web platform installer. I am trying to add the porter stemmer module but no matter what version I choose, I get this error</p>
  
  <pre><code>Warning: mkdir(): File exists in DrupalLocalStreamWrapper-&gt;mkdir() (line 639 of C:\Users\myuserid\Documents\My Web Sites\acquia-drupal7\includes\stream_wrappers.inc).
