do?

Answer 1

This is a Unity bug, they changed the license verification process, and after upgrading to 2017, not everyone has the engine files updated correctly. Relogining to a unit account helps someone, someone does not. You can also try deleting files as described here . It disappeared after a couple of reinstallations.
