Hey guys, I’ve installed UE 4 and the first time I used it, it worked amazingly, the issue I’m having now is that when I open the launcher instead of a launch button I’m getting Download error. Retry? I’ve tried for a day now and have had no success I’ve uninstalled and reinstalled it, if anyone knows anything that might help I would be forever grateful.
I’ve tried the extra lines in the defaultengine.ini with no luck so far and I am unable to even open the editor as i have to go through the launcher to open it.
So I solved it by simply logging out and logging back in ._. something so simple and it took me a day to figure it out thank you for all your help guys 
I have the same issue with Unreal Engine launcher but UE4 Editor work.
