Unable to find, or open, Cubase AI 11

I have recently purchased an audio interface (UR22 MK2). Downloaded Steinberg Download Assistant, and the folders associated with Cubase AI 11. However there doesn’t seem to be a folder that opens the main Cubase program.
I open the Cubase AI 11 folder and that just takes me to a folder that opens the Cubase installer again. I’ve attached images
I’ve downloaded the software onto a Macbook Air, same problem occurs
eLicence is set up fine
Can anyone help? Online support has not helped so far!
see attached images
