title: Installing RMagick on Windows
body: <p>I've done research on this and I've been at it on my one computer for hours and hours.</p>
  
  <p>I've installed RMagick on my Desktop computer about 3 weeks ago, and it was fairly complicated.</p>
  
  <p>I don't remember the exact steps I took, and I'm really frustrated. </p>
  
  <p>I've installed ImageMagick onto my machine in the directory C:\ImageMagick</p>
  
  <p>I've installed the Development kit too for Ruby.</p>
  
  <p>I've also put the rmagick-rmagick-v2-2-g564f157 into the proper gems folder in my C:
  It's in C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems</p>
  
  <p>I'm getting the following errors:</p>
  
  <p>I will type: <code>gem install rmagick -- '--with-opt-dir="c:\ImageMagick"'</code></p>
  
  <p>and get the following errors:</p>
  
  <pre><code>Temporarily enhancing PATH to include DevKit...

  <p>I'm so frustrated at this point. It worked on my Desktop computer, but won't work here. Any suggestions?</p>
