title: .Net Installer repair option
body: <p>I am working on a project, where I need to give a repair/remove option to my installer [which will be shown at installation time] if the program previously installed. And I need to do it with VS 2008. Please help me on that. </p>
  
  <p>EDIT: Actually for some security reason I removing registry entry for previous installation. So that I can uninstall it from my application only, which is password protected. So thats why I need to customize that repair/remove option. So that it will appear by seeing some specific registry value. How can I do that ?</p>
  
  <p>Thanks.</p>
