Hai and Vanakam to everyone…
I had the same problem when i tried to update 4.11…
I got error message(Could not download installation information. Code: 0 . Please try again later)…I followed many solutions from UE4 ANSWERHUB but nothing worked for me…
Then i tried the following solution and then my problem got solved…
1.First I copied 4.11 FOLDER from(D:\Program Files (x86)\Epic Games) to my local drive.
2.Then uninstalled 4.11 from Epic Game Laucher.
3.After that I pasted 4.11 FOLDER to(D:\Program Files (x86)\Epic Games).
I am using D drive for Epic Games(Many are using C drive)
Then I tried to install Unreal Engine 4.11 through Epic Game Laucher. After taking some time it shows Launch Unreal Engine 4.11.0…
