So, my laptop crashed and i had to reinstall unreal engine. i downloaded epic games launcher and it was working, but for some reason it refused to download version 4.7, so i reinstalled the launcher. now, every time i open the launcher, a window pops up saying ‘EULA error’. i looked through some of the previous posts… but they didn’t help. i’m not sure if its because those files like ‘EMS’ are missing or if its something else… what do i do to fix it? 
Hi JuliaShiban,
Take a look at the solution that Maximusdb3 posted here. Let us know if that works for you or not.
omg yes it finally started working again! thank you so much
