title: ActiveX Control will not load [Win XP, Vista]
body: <p>I have an application that is trying to load an ActiveX control residing in a signed cab file on the server.  When I try to run the function that loads it, I'm stopped by the IE information bar with the following message:</p>
  
  <p>In IE 6 &amp; 7 - "Your security settings do not allow websites to use ActiveX controls installed on your computer"
  In IE 8 - "An add-on for this website failed to run"</p>
  
  <p>When I look at the error file that gets dropped in the browser cache, it shows error 800b010b (Generic trust failure).</p>
  
  <p>This is all happening in the Local Intranet zone, and I brought the IE security settings to minimal, enabling every option available.
  I later added the website to the Trusted Sites and set everything to Enable there too, no change.</p>
  
  <p>These tests are on multiple machines, XP and Vista.
  I am logged in as an admin on all of them.</p>
  
  <p>If I replace the cab file with one that I gave a dummy signature, it works.
  If I replace the cab file with one that is not signed at all, it works.
  If I try to run the one with a non-expired VeriSign signature, it fails.</p>
  
  <p>At this point I'm not sure what to check.  If anyone has a clue, I'd love to hear it.</p>
