title: "msvcrt-ruby18.dll was not found" with Ruby
body: <p>When I try to run even simple rails commands such as:</p>
  
  <pre><code>rails -h
  </code></pre>
  
  <p>I get a popup error after a few seconds that says:</p>
  
  <blockquote>
    <p>ruby.exe - Unable To Locate Component</p>
    
    <p>This application has failed to start
    because msvcrt-ruby18.dll was not
    found. Re-installing the application
    may fix the problem.</p>
  </blockquote>
  
  <p>I am running:</p>
  
  <ul>
  <li>Windows XP (yes I know I should attempt ruby on a Windows machine).</li>
  <li>Ruby 1.9.1p378 [i386-mingw32].</li>
  <li>Have updated all my gems to latest versions (as of 14-July-2010).</li>
  </ul>
  
  <p>Is there a way I can test what is making this error? Does anyone know what it could mean?</p>
  
  <p>I have found that in my <code>ruby19/bin folder</code> there is <code>msvcrt-ruby191.dll</code> but there is no <code>msvcrt-ruby18.dll</code> anywhere. Why would it be looking for this anyway if I'm using ruby 1.9?</p>
