I can not start my UE4 launcher. it says: “Error! No version information received.” Today has just bought UE4, this is the first time to use. Believe me, I have tried all the ways, did not solve the problem. I’m sure my network good, I am also the administrator user, and not behind a proxy. Why?! …

Hi zym1983811, Have you tried restarting the launcher and/or restarting your computer? This is the most common solution when this issue occurs. Thanks
