"I found out how to fix this guys , i dragged my setup tool to the desktop this seemingly updated it to the new downloader screen that they recently updated , Im guessing this was the problem , if you guys are still having problems there are plenty of forum posts out there explaining how to get the new installer , I also think you can get it from the Battle.net website"
Apparemment problème solvable avec un "nouvel installeur" obtenu sur le site battlenet.
