When I try to load Photoshop CS version 8 I get this message

You can’t open the application “Install Adobe Photoshop CS” because PowerPC applications are no longer supported.

What am I doing wrong?

Photoshop CS was written for PowerPC processors, and predates Apple's move to Intel processors.

You will not be able to run PowerPC code on MacOS 10.10 -- your only option would be to upgrade to a current version of Photoshop that runs Intel native code.
