Hi All,

I'm trying to use MSHTML from a Console Application as a Parser.

    hr = Location.CoCreateInstance(CLSID_HTMLLocation);

is returning 'COM Error: 0x80040154 (Win32: 340)'

If I try to get IHTMLDocument2 to initialize IHTMLLocation

    hr = Document->get_location( &Location );

'COM Error: 0x80004002 (Win32: 16386)' is returned.

Any ideas? I've duplicated on two machines.
