title: Xampp-installation problems; ports not free and Apache not starting
body: <p>I tried installing xampp from the following site: <a href="http://www.apachefriends.org/en/xampp-windows.html" rel="nofollow">http://www.apachefriends.org/en/xampp-windows.html</a></p>
  
  <p>I had problems installing. When the control panel runs, it shows green signal for MySql and Mercury only, and especially when I start Apache, it gives an Exception.</p>
  
  <p>And at some point it says to disable UAC, but I guess that is not recommended in Windows, so what should I do? </p>
  
  <p>And I also received an error which said "class not registered".</p>
  
  <p>The following are the errors I receive when I start Apache:</p>
  
  <pre><code>11:27:40  [Apache]  Problem detected!

  <p>Where are these logs buttons? And from where to free the ports?. I don't use Skype so my port 80 is probably free. Please help.</p>
