That would be ERROR_INVALID_HANDLE
(http://msdn.microsoft.com/en-us/library/windows/desktop/ms681382%28v=vs.85%29.aspx).

The third party tool is probably attempting to use an invalid handle.
Most likely, the handle was valid but is now closed (or is set to
INVALID_HANDLE_VALUE). Note well (N.B.): INVALID_HANDLE_VALUE is
different than NULL, and its easy to mix the two up. For example, some
functions return NULL on failure, others return INVALID_HANDLE_VALUE.
It depends on the context/object, and you have to pay attention to
details on the Win32 call.
