Install Error Code 0

Hi there. I was trying to install unreal engine but it is always showing error code 0. I even thought about building from source but no luck (I am still not able to get those repositories though I linked my account - @BrainBuzzer on github).
BTW, I was able to download once before but got some other error and I was supposed to uninstall and reinstall it, but since then, no luck. Before you ask for any logs, here are they:

Hi dtrg21,

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…
