title: perl: cannot unlink file: Permission denied at C:/Strawberry/perl/lib/File/Temp.pm
body: <p>I am trying to run a perl script using selenium webdriver.
  After successful execution of script, I am getting following error:
  *</p>
  
  <blockquote>
    <p>cannot unlink file for
    C:\Users\\AppData\Local\Temp\89qNk6oDJh\cert8.db: Permission
    denied at C:/Strawberry/perl/lib/File/Temp.pm line 1616.</p>
  </blockquote>
  
  <p>*</p>
  
  <p>And the line 1616 in Temp.pm looks like this:</p>
  
  <pre><code>eval { rmtree($self-&gt;{REALNAME}, $File::Temp::DEBUG, 0); };
  </code></pre>
  
  <p>What can be the cause?</p>
  
  <p>My script is simple perl program, it creates a webdriver object and open a URL and gets the title.</p>
