I contacted Adobe, they gave me step by step to install my CS3 on my iMac Mojave. I believed to have followed every step. However, when I downloaded their install of CS3 onto my Mac, it seems to be giving me trouble. I clicked on SETUP, but it gives me a message of "Setup" is an app downloaded from the internet. Are you sure you want to open it?" I say OPEN, bounces then disappears. I turned off firewall. I am not sure what I am missing? Please HELP!

    The OS version that CS3 is guaranteed to operate is up to 10.5.
    Later operating systems are not supported.
    Since macOS is an incompatible OS, it is impossible to run old applications.

      Bear in mind CS3 cannot run in Catalina, even if you find a lucky break in Mojave. Apple have decide all old apps must die.

      Apple did not maintain backward compatibility, so try this to install old programs
