# How to render latex in-line with org mode?

I have a file with the following contents:

Math Notes -*- mode: org -*-
#+STARTUP: latexpreview

Test $\forall \epsilon > 0$


I am trying to render the latex with C-c C-x C-l, but it's not working. My .emacs.d file is taken straight from this gh repo. Could someone please offer some advise on how to debug this? Thanks!
