How can install ue4 after do a new system windows without download again

I make a new system window and i want to install unreal engine 4.7 witout download it again i have all engine file i take C:\Program Files\Epic Games. all files

Hi Ahmed,

I would suggest the following:

  1. Install the Launcher on the new computer
  2. Close the Launcher after it launches
  3. Copy the 4.7 folder from C:\Program Files\Epic Games on the old computer to C:\Program Files\Epic Games on the new computer
  4. Launch the Launcher and sign in
  5. Go to the Unreal Engine > Library tab and add a new engine slot via the “Add Version” button.
  6. Change the slot to 4.7 if it is not already set and click Install

The Launcher should download a very small amount of data and then immediately switch to “Installing”.
