Can't install Unreal Engine at all - Very Stuck

Above is a screenshot of my Epic Games Launcher, the button is greyed out and when I click install nothing happens at all. I’m very confused and would appreciate any help provided.


I have actually solved this issue, for anyone who experiences this. I had to click on the UE5 tab, and then click download early access. After this I was able to install 4.26.2.
