Math formula generator can't find the path.

Summary:

When I have TexLive installed from the official distribution (Manjaro) the extension works perfectly.

However, I recently uninstalled it and installed a portable and complete version, providing the environment variables: PATH, MANPATH and INFOPATH. I did this according to https://www.tug.org/texlive/doc/texlive-en/texlive-en.html#x1-300003.4.1

The result is that the extension does not appear clickable. I guess it doesn't recognize the PATH.

Steps to reproduce:

• open Inkscape
• open Extensions
• open Render
• open Mathematics
• I can't use the LaTeX extension (pdflatex).

What happened?

Does not appear clickable.

What should have happened?

It should appear clickable.
