Before any login textboxes displayed, just after start of launcher. When it try to update it does very small download, few (1-7KB) kilobytes and download speed fast decreasing to 0 and it waiting forever for next few kilobytes. After some minutes (Eg. 5 or more) it downloads again few kilobytes and again it waiting). In this way it will start that launcher in few days.
Already killed application over 5 times. I’ve tried it in admin and in normal windows user mode. In admin it does download a bit more kilobytes at start, but after this it stops and waiting with 0 download speed. I suspect update server overcrowded or no free seeds if GW2 use torrent technology. That’s annoying as i have very limited time for daily gaming.
P.S. Europe, ultra fast 100mbps optical fiber internet connection. In my side no any issues. I even shutting down Skype while i play games.
Already updated, but it taked around 15 minutes to update launcher… After update i closed launcher, not logged in. As i don’t use admin if i don’t need it and started launcher again without admin rights and it again updates launcher…
