Here on my system for example the entry there is not a path but simply "pdflatex.exe", and I guess just "pdflatex" would also work. The thing is that the Latex installation is registered in the relevant system search paths, and so this command is enough. If just doing "pdflatex" (obviously without .exe on a Mac, but perhaps .app, I don't know about that) doesn't work for you, my guess is that the Latex installation hasn't registered itself successfully. But how it does that is not something that gretl can document I'd say, as there exist several Latex distros. Also you mention "the correct pdflatex file", do you have many of those lying around? cheers sven
