What am I doing wrong? What do i have to install?
Hi, I think unreal gives you information about missing files.
Read that filenames, google them and see what windows updates they are part of.
Generally it will be microsoft .NET and some packages for visual C and Direct X.
Before you click ok to those error messages see what filenames unrteal complains about.
You could also try uninstalling the Epic Games Installer and then re-installing it, because there could be a corrupt file which is read wrong. That could be your problem. It happened to me once in the past and by re-installing the Epic Games Installer I managed to download Unreal Engine with no problems.
