[XeTeX] Problem deciding Family Names

TrueType fonts are searched for by the Kpse variable TTFONTS.
The default value is
TTFONTS = .;c:/{winnt,windows,winnt35}/fonts//;$TEXMF/truetype/fonts//

OpenType fonts are searched for by the Kpse variable OPENTYPEFONTS.
The default value is
OPENTYPEFONTS = .;$TEXMF/fonts/opentype//

W32TeX has only two texmf trees: texmf and texmf-local (initially empty),
namely
TEXMFMAIN = Root/share/texmf
TEXMFLOCAL = Root/share/texmf-local
TEXMF = {$TEXMFLOCAL,$TEXMFMAIN}

You can copy OpenType fonts under
Root/share/texmf-local/fonts/opentype/
