Hello everyone! I am brand new to using Unity and am currently trying to take the “Complete Unity Developer” course. However, it seems I have run into a problem while trying to bring up Unity 4.6.
I previously had Unity 2017.3 downloaded, but I uninstalled that version to install 4.6 to follow the course with. With Unity 2017.3 I was able to bring up Unity without any problems, but with 4.6, it is telling me "A valid license is unavailable."
If anyone could contact me with a solution, or any advice to this problem as soon as possible, I would very much appreciate it. Thank you.
