After effects not downloading

I have just bought a brand new MICROSOFT 14" Surface Pro OLED, Copilot+ PC - Snapdragon X Elite ideapad

I am trying to download after effects, however, it will not install. 

On my creative cloud, it only shows the online beta version (which is not what I want). When I use the browser to download the app, it downloads the set up file. 

After double clicking on the set up file (+ trying run as administrator), it just opens my creative cloud again but doesn't install. 

what can I do?
