It would be a complete waste of time to contact Adobe about running CS6 in anything beyond Mojave. I don't know what TheLittles even bothered to mention it. On top of that, Adobe considers CS6 abandoned software. You can't even download updates for it from their web site anymore (glad I saved all of them to an external drive).
As was correctly mentioned, while the CS6 titles are mainly 64 bit apps, they have a number of 32 bit dependancies that will not run in Catalina or later.
If you want to run CS6 in Catalina, the only way to do that is to first install virtual machine software (VMware, Parallels, VirtualBox). Second, install an older version of the Mac OS in the VM as a guest OS. Nothing later than High Sierra would be best for CS6. Lastly, once the guest OS is installed and running within the VM, install CS6 within that.
