Hello pour ceux qui ont des problèmes avec le téléchargement j'ai trouvé la solution (du moins ceux qui bloquent à 77%) sur un forum anglais:
I'm not sure if this 'really did' have any effect, but I'm inclined to believe this fixed my stuck at 77% issue.
Apparently a common thread with the downloader/installer is it draws its connection settings from your IE browser connection settings, so for me I went into Internet Explorer, Internet Options, connections, Lan Settings. Uncheck auto detect settings.
Close I.E. and in my experience it took a few seconds, I thought nothing was happening and then BAM! Zipped up from 77% in just a few short seconds.
En gros ouvrez I.E Options Internet => Connexion => paramètre réseau privé => Décocher la case détection automatique => Fermer I.E
En espérant avoir aidé
