I'm trying to run feymp-auto to run with MikTeX (in TeXniccentre). On an earlier post:
Feynmf doesn't produce feynman diagram at all in TXC
egreg commented:
"For this to work with MikTex you have to add the -enable-write18 switch to the argument list of (pdflatex)."
Does anyone know how exactly do you do this? Is it in the "build output profiles"?

This is what I've done, doesn't seem to be making a difference though.
Addendum
It works now, I didn't realise you had to run it twice!
