This is the first time i use Unreal Engine, after the first lunch, and when traying to download Unreal Engine 4.1, i get ALWAYS “Download error. Retry?”.
I have a good internet speed, so maybe the problem is from the Unreal Engine Server ?
Please Help!
Just try it some more times (close the launcher and reopen it) and also make sure that you run it with admin rights.
The question has been asked before, but unfortunately nobody found a solution

i add an exception on the firewall, also disable anti virus… but the download didn’t work !
After many many trying, finally the download has been started correctly 
Hi mGames.
Sorry to hear that you had difficulties with this. Glad it eventually worked, but we will investigate to try to prevent issues in the future.
Cheers!
