Legacy Java Message

Still getting this exact message on startup: To open “CS5ServiceManager” you need to install the legacy Java SE 6 runtime.

Click on “More Info...” to visit the legacy Java SE 6 download website.

I have tried several ways to get rid off as suggested online. They include going to More info, then updating Java with oracle; I now have Java 8 Update 251. I unchecked the Check for Updates Automatically box. I deleted all Adobe CS5-related apps. I still get the message on startup. What should I try next? Should I use a Mac cleaner? Can I delete Java totally? Start over with a new Java? I have macOS High Sierra Version 10.13.6.

Please help for I am at a loss here.
