Go to d:/w32tex/share/texmf/fonts/conf
and edit the file fonts.conf:

<dir>c:/windows/fonts</dir>
<dir>d:/w32tex/share/texmf/fonts/opentype</dir>
<dir>d:/w32tex/share/texmf/fonts/truetype</dir>
<dir>d:/w32tex/extfonts</dir>

(Add the above three lines after the existing line)

After saving the file fonts.conf, run a command
fc-cache -v

Best regards,
Akira
