title: Uninstalling Xamarin on Windows
body: <p>I want to remove previous Xamarin from my machine and install a new version (Xamarin Visual Studio 3.9.236), But when I try to install the new version I'm getting this error:</p>
  
  <blockquote>
    <p>The older version of Xamarin cannot be removed. Contact your technical
    support group.</p>
  </blockquote>
  
  <p>Any Idea?  </p>
  
  <p>PS: I went through <a href="http://developer.xamarin.com/guides/cross-platform/getting_started/installation/uninstalling_xamarin/#Uninstalling_Xamarin_on_Windows" rel="nofollow noreferrer">this article</a> but I still have the same problem.</p>
