Unreal Engine 4.14.3 Fails to Launch, Please help

Hi Everybody.
I am new here,

I have installed UE 4.14.3 in my Work PC, and I would like to get a copy for my personal system as well. And when I say copy, cause I have very slow internet speed and installing a fresh copy of UE is impossible.
Coming across various articles, I found an Academic Installation which said I had to install complete UE in one system and copy certain data from folders to mirror the setup on other PC’s.

Now the Epic Launcher recognizes these new updates but fails to launch any of them. When I click Launch on any version, It says BUSY and gets back to Launch icon again. I tried opening projects directly but it says “Failed to Launch Editor”
So when bypassing the launcher and running the editor from \Epic Games\4.14\Engine\Binaries\Win64 it say VCRUNTIME140.dll is missing. So I downloaded that .dll and placed it in the directory but these missing .dll’s keep popping up one after the other.

Can anyone help me out with this?
