How can I install both fonts in the page http://www.tug.dk/FontCatalogue/garamondx/ to work together? My attempt so far was installing both as OpenType system fonts and using XeLaTeX with no success. I'm currently using TeXworks and MikTeX on Windows 7.
garamondx package and the URW GaramondNo8 fonts are not included in either TeX Live or MiKTeX because of their restrictive licences. The easiest way to install them is through the
getnonfreefonts script—see the instructions at
