Hello! In my environment, I think it is a bad idea to rely on any windows fonts being available in every system now and in the future, so I keep the fonts I need with my project and specify the path to them. I want to choose my fonts for my document needs, and "is installed on this corporate windows PC today" is not an important font property.
It works well, but I admit I have not fully understood everything involved. \usepackage{fontspec} \renewcommand{\familydefault}{\sfdefault} % http://projekte.dante.de/DanteFAQ/Schriften#19 % Siemens Professional OTF \setmainfont{SiemensSerif_Prof_Roman.otf}[ Path=C:/SIBAS32/BETA/DPS/tex/Siemens_Professional_6.0_beta_OTF/, % Suchpfad nehmen BoldFont = SiemensSerif_Prof_Bold.otf , ItalicFont = SiemensSerif_Prof_Italic.otf , BoldItalicFont = SiemensSerif_Prof_BoldItalic.otf ]% Maybe for the original poster's colleague, specifying the PATH in setmainfont is enough, maybe choosing the fonts and storing them with the document classes and styles is the way to go?
