Install CS5

[Diane_Epstein]

I replaced my logic board on new Mac Book Pro version 10.13.1 High Sierra.  Photoshop did not appear so I downloaded it from Adobe however, after trying several times, I keep getting the same message: "Install" can't be opened.  You should eject disk image.  I would like your help in downloading and installing CS 5. Thank you.

Also you'll need the legacy Java 6 runtime from here:

Install it before cs5.
