Banishing residual Adobe components pre upgrading a mac to a 64 bit OSX.

Hi all, I hope you're surviving the late Feb. storms - I am in the process of shifting from Mojave to Catalina and see in the mac's "System Information / 64 bit column" that there are A LOT of Adobe components there that are not 64 bit.

That seems to suggest they are no longer needed for CC [as they won't operate on 64 but mac OS]? 

I am guessing they are leftovers from the CS3 suite which I was using up 'til I switched to the subscription version. 

The applications are long gone (manually delted, maybe that was a mistake). 

This help page isn't much use because it seems to suggest deleting components that will be part of the CC install. https://helpx.adobe.com/x-productkb/global/delete-previously-installed-application-files.html

Maybe others a "remove" utility?

Or perhaps I have to manually delete all of the ones listed below:

any help much apreciated

this tool seems unhelpful as its apparently designed to remove CC apps, not what I want.

Nothing in Adobe Help for " remove Creative Suite apps"

thanks lots
