Finding HRESULT '-2146697191' Error message - clickonce setup error

I want to know what exactly 开发者_如何学PythonHRESULT 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?

For reference here is the error log in short:

HRESULT -2146697191 (0x800C0019) means "The Secure Sockets Layer (SSL) certificate is invalid." See INET_E_INVALID_CERTIFICATE.

Also it would be great if anyone can tell me how to lookup for error message if HRESULT is given as decimal number?

The way I do this is to enter the number into the calculator and then switch to hexadecimal display.

In this case it gives FFFFFFFF800C0019. Removing the leading Fs gives an error code of 0x800C0019 which will be searchable.
