During my search I did find this site. There is a link on this page that says "If you are looking for the latest product updates for Creative Cloud, please click here." This then takes you to Explore Adobe desktop apps | Adobe Creative Cloud. When I tried to download Photoshop from this location it opened up in Creative Cloud and I received the same error.
I am hoping to find a link to the 14.2.2 update that I can download manually but it doesn't seem like this is available.
