Since none of those OSs are “current,” I’d only bother attempting it on Sierra via a clone of your current system or perhaps a VM. It might also work on High Sierra and Mojave, too, but definitely not on Catalina and beyond (Catalina requires 64bit apps, and CS4 on the Mac is 32bit). In principle, you should be able to run CS4 just fine on a VM running Sierra. It’s too bad the 4 updates just didn’t work.I’m going to do something crazy and reply with a direct answer to original question. PSE 2022 doesn’t seem worth it, or I’d consider getting the Nik 5 Collection. My Nik 4 always worked perfectly until the 4.3.4 update.

Maybe they’ll have me manually add the Nik Collection to the Plug-Ins folder? Btw, there are two graphs on the DxO site, one saying the newest update to the Nik 4 Collection is not compatible with PSE 2020, and another saying that it is. I see all the DxO/Nik files in the PSE 2020 Support Files folder, but they’re not in the “Plug-Ins” folder, they’re in a DxO folder. I tried adding the Nik Collection via PSE 2020 Plug-Ins “Choose” from preferences, but after clicking ok and restarting, they never showed up. There’s no Selection Tool and no path to Nik apps. Today I downloaded the latest version of the 4 Nik collection, ok’d adding to PSE 2020 as a plug-in, but it didn’t do it. DxO techs did offer some suggestions but they haven’t worked so far. It’s too bad I can’t easily use Nik Define, etc., or Color Efex right from PSE, but, I’ve learned to live with it. I reinstalled PSE 2020 without adding the Nik Plug-Ins and it works fine now too. Update: I have been using Nik with DxO Lab and sometimes as standalones. If I understand what you’re saying, by renaming the selective tool, and adding Nik back to the PSE 2020 plugins, everything should work? What did you name it? Can it be deleted? We need the selective tool for the apps, don’t we? I looked for a 4.3.5 update but couldn’t find it and my support person didn’t offer it after I mentioned someone else had gotten a link for it. I just uninstalled and reinstalled PSE 2020 so I have that again, and figured Nik products would no longer be supported through it, which is a shame. I had sent them a DxO diagnostic program run through terminal that I realized later was more invasive that I should have allowed. I recently stopped responding to my DxO support person because she consistently failed to grasp the problem, asking what hosting platform I used when it crashed, etc., etc., and wanted me to run ‘mac-clean-pse-20.sh’ through terminal, but I got security warnings doing that and stopped.

I can’t thank you enough for your efforts to help with this matter.
