I don’t understand why I am spending so much of my time on this.

I downloaded a version of CS4 and this is the mesasge I got when I opened setup:

Setup can’t be opened because it is from an unidentified developer.

Your security preferences allow installation of only apps from App Mac App Store and identified developers.

Setup is on disk image ADBPHSPCS4_LS1-3dma

This should be easy in my opinion and its not!

That message is nothing to do with Adobe. It's your Apple Mac operating system's feature called Gatekeeper kicking in.

Just right-click then click Open.
