Adobe creative cloud won't let me install photoshop on my macbook pro

I recently uninstalled photoshop and now I'm trying to reinstall  it on my macbook pro 13" retina display. When I hit download this message pops up,

"You are running an operating system that Photoshop no longer supports. Refer to the system requirements for a full list of supported platforms."

I checked my computer settings and it meets all of the requirements.  My computer has illustrator and inDesign installed. I tried installing other apps but no adobe apps will download on my mac. How can I fix this problem?
