Download MeGUI AviSynth Wrapper test.

I think it works not only for AviSynth+ but for avs2.6 or newer in general.

Copy over the existing one.

Probably the old one bundled with MEGUI was compiled with an AviSynth CPP 2.5 header.

The bundled DLL set is a "bit" old as well.
The x64 CPP 2.5 plugins are especially outdated.
