OK, now I’m confused about where the error is coming from.  I tried it
myself, also adding the .otf extension for some runs, both with XɘTeX &
LuaTeX, and always get a similar error.

Actually this is a real answer; my reading of the fontspec manual
suggested that the [<style>Font = <whatever>] options needed file names
rather than font names.  Turns out, not so much:
	\documentclass {minimal}
	\usepackage {fontspec}
	\setmainfont[
		BoldFont		= * Bold,
		ItalicFont		= * Italic,
		BoldItalicFont	= * Bold Italic,
		SmallCapsFont	= * Small Caps,
		Ligatures = TeX
		]{Fontin Sans}
	
	\begin {document}
	foo \textit{foo \textbf{bar};} \textbf{bas} \textsc{quux}
	\end {document}
This works just fine.

Thanks,
