Copy ARCHD3D.EXE into your Daggerfall directory.  It requires a full install as it
looks for the data files in the ARENA2 directory.  The progam was written using 
Direct3D 1/2 so it is very simple.  Textures are messed up and display differently
on different DirectX versions, and you may be better off playing around in wire frame
mode.  This is simply a test program so some things may work, or not at all.
