Hi Ahmed, I am trying to download the proTeXt ISO image but I am unable to access the FTP link provided on https://www.tug.org/protext/
I don't know what happened to ftp.fernuni-hagen.de (I assume that's what you're referring to). Thomas? The hostname no longer resolves in DNS. In any case, you can download protext from http://mirror.ctan.org/systems/windows/protext. That automatically chooses a nearby CTAN mirror. If the one chosen does not work, you can select one manually from https://ctan.org/mirrors and then navigate to systems/windows/protext in that mirror's interface. Hope this helps, Karl -- http://tug.org/protext/
