I was trying to open Unreal Engine Launcher but this message appears

When i press OK, another window appear with this message

I read in another answer that uninstalling and trying to install again will probably fix the problem, but i cannot download, because the link on the main web page is broken…

Now i don’t have unreal engine installed and i cannot install again because i don’t have the installer… Any help?

Hi again… Today i was able to download again Unreal Engine and now i’m installing (downloading all the stuff)… For the moment everything looks fine… thanks anyway…
