I’m trying to re install the latest UE after constant crashes when using cascade. I uninstalled completely… but it keeps coming up with the error message “target directory needs to be empty” I have no idea what directory or where to find it… anyone shed any light as to whats going on…?
When do you get this message? When you install the launcher or the engine? 
Regarding the cascade crashes -> when you have a crash, make sure to report/post them on answerhub
