title: Finding HRESULT '-2146697191' Error message - clickonce setup error
body: <p>I want to know what exactly HRESULT error means? This is occuring when user is trying to download clickonce application from our server. Hence to figure what is the problem behind it I want to know what does this HRESULT number refers to. I tried to use error lookup tool but it says message not found. Is there any way to find this error message? Also it would be great if anyone can tell me how to lookup for error message if HRESULT is given as decimal number?</p>
  
  <p>For reference here is the error log in short:</p>
