I need adobe photoshop 2020 back 22.2 doesn't work and the newer one won't install

Hi @MiguelEzquizofrenico,
Only the latest two versions of the Creative Cloud apps are supported and available for download. Also, Adobe has discontinued publishing public download links for installers since CC2020. Hence, the only option to get an installer for CC2020 would be to contact Adobe support, they will provide one it they have it handy. To contact support follow the instructions given below
1. Go to https://helpx.adobe.com/contact.html?rghtup=autoOpen
2. Wait a bit on the page that opens up, it should automatically open a chat popup. If that does not happen then look for a call out/chat icon at the bottom right, click over it and the chat popup should open
3. In order to talk to a human type "AGENT" in the chat box
4. If you are not able to get to the chat window, then disable your adblockers, firewall, enable cookies/scripts on your browser. If it still fails then change your browser/machine/network.

P.S. Be mindful of answering anyone who sends you a private message. See the following for more information about scammers
