Install button for ue4 on epicgames platform not working

So i installed epic games platform, when i click on the yellow ue4 button, nothing happens. How do i install ue4, NOT Epic games. The platform is successfully installed already and account setup, so please no “first install epicgames” stuff please. This should not be that difficult to install tbh.

Thanks in advance

try if the button in the library tab works
