@DeWetAtSafe: I found your archlinux package of fme desktop 2017 at
https://aur.archlinux.org/packages/fme-desktop-2017/
I tried to re-pack fme desktop 2018 using the files for 2017 as a template, albeit unsuccessful.
Would it be possible that you create a package for the fme desktop 2018, too? That would be most helpful!
