In my texlive 2016 (in windows) the fonts are otf and not ttf-font,
so using ttf as extension leads to errors. 

Beside this I get the error if I use the UprightFont-key, which
looks a bit senseless anyway. 

This works without problems:

\setmainfont{cmunrm.otf}[BoldFont=cmunbx.otf,ItalicFont=cmunti.otf,BoldItalicFont=cmunbi.otf]
