Texstudio does not recognize a font (STIX Two) in \fontspec package

Question

I am using Texstudio with miktex and lualatex, both of which I downloaded yesterday. I had a file that compiled perfectly on overleaf, but here a thousand errors pop up when I try to run the code. These are the messages I get: "Package fontspec Error: The font "STIXTwoMath" cannot be found. \fi" , "Font \TU/STIXTwoMath.otf(0)/m/n/10=[STIXTwoMath.otf]:mode=base;language=dflt; at 10pt not loadable: metric data not found or bad. \fi", "Package fontspec Error: The font "STIXTwoText" cannot be found. \setmathfont".

My best guess is that the font names change between Overleaf and TexStudio (or Miktex? I don't really understand what is what, sorry about that), but I do not know where to check the list of the full catalogue of fonts and their names in each editor.

Here is a sample code that does not compile:

\documentclass{article}

\usepackage{lipsum}
\usepackage{fontspec}
\usepackage{unicode-math}
\usepackage[spanish,mexico,es-noshorthands,es-noindentfirst]{babel}
\usepackage[tracking=true,protrusion=true]{microtype}
\setmainfont{STIXTwoText}
\setmathfont{STIXTwoMath}

\begin{document}
    \lipsum[1]
    \[ \alpha, \sum, \int \]
\end{document}

Thanks everyone!

Answer 1

hopefully this will be useful to someone in the future. The reason the error popped up is because, using windows and miktex, Stix fonts are not installed by default. They need to be installed separately from the official link: https://www.stixfonts.org/

Once installed, everything compiled correctly.
