Oh, and, this is probably obvious and well-known, sorry if I'm
teaching grandmother to suck eggs here, but if you have rights to
distribute this DLL with your application, I understand this means
that you own a copy of Visual Studio, and a copy of the DLL and
manifest file can be found in the installed Visual Studio 'redist'
directory. If you don't have such a DLL in that directory (eg. if you
have the express edition) then you don't have legal right to
distribution it. Just so you know.
