My photoshop cs5 does not work after installing Catalina.

My photoshop cs5 does not work after installing Catalina. I need an easy way to uninstall and reinstall previous operating system. Does anyone know how to do this or is there an alternative? I do not have the copy of photoshop anymore or the serial #s!

Thank you in advance!!

Just to point out, if this is a copy of Photoshop that someone else put on your Mac, or sold with it, you are using illegally obtained software. It isn't, and was never yours.


If you did purchase it but have lost the packaging (where the installation disk and serial number would be), you can retrieve the serial number by logging into your Adobe account, assuming you registered it at the time of purchase. All purchases you've ever made are there, along with their serial numbers.
