title: How can I make the installer Run as admin
body: <p>My application has an installer built in installshield. 
  But for proper working of installation process in vista Win 7 etc. the installer should be run as administrator. (Even though the user has admin previlege he should select the 'Run as Administrator' option in the menu on rightclicking the installer exe)</p>
  
  <p>How can I make my installer to prompt that it should be always run as administrator.</p>
  
  <p>Thanks in advance...</p>
