Using UE4 on another PC (kind of)

Hello people :frowning:

I’m in a really big problem here… I had downloaded and installed UE4 on my laptop (which is not mine actually, it’s my brother’s). Now my brother (for some stupid reason like always) reinstalled windows. I had no choice but just to copy the complete UE4 folder in a USB drive. Now it doesn’t work (of course I knew it too). Now I live in a country where internet is simply expensive and I cant just download almost 5 gigs of data again… Is there any way to edit the registry or something to get it working somehow ??
