Can't install faf

Just got my new PC and i'm trying to install FaF after downloading the client installer from the site, but nothing happens when i double click it.
Computer starts loading, and eventually i get "you need to download an APP in the windows app store to run this".

I have never had this problem or this error message before on my previous PCs, what might this be?

It just refuses to launch the installer.
I currently run win11.

The official client? Yes the FaF client that you download of
