"Type library importer has encountered an interface not derived from IUnknown: '_HiddenInterface'."
I am getting this warning after adding a reference to a vendor's COM dll in VS2005.
What does this mean and should I be concerned. I am able to use the COM object without any issues but I am unable to get rid of the warning. Also when I add the reference, 2 other references are added "MSXML2" and "VBA".

This is because the vendor has broken one of the fundamental rules :-)
I probably wouldn't worry about it too much, it will be the same for any other COM client. The references are added because the vendors COM uses them.
