title: How to install the "BHOManager CLASS" add-on in IE
body: <p>This "BHOManager CLASS" add-on is a supporting add-on to run QTP script on the IE browser.</p>
  
  <p>The publisher of this add-on is Mercury Interactive Corp.</p>
  
  <p>I have uninstalled the existing IE browser because of some issues in my machine and reinstalled it. And after this i cannot run the QTP script as the "BHOmanager Class" add-on is missing.</p>
