You already have the correct answer: Catalina requires 64-bit apps and does not support 32-bit apps.


Which means you will need to wipe and re-install macOS Mojave or similar, or install on external storage as suggested above, either of these if your Mac predates Catalina and can support booting from an earlier macOS version. Or you will need to install a hypervisor, and load Mojave into that, and run your app within a Mojave guest. Or find a replacement for the 32-bit app(s).
