My friend has upgraded her Apple iMac to Apple's Mountain Lion (OS10.8.2) operating system. We want to install Photoshop OS3 from an installation disc, which worked fine with the old Snow Leopard operating system, but now refuses to install.

This is the message that flashes up when an attempt is made to install from the disc: "You can't open the application 'Install Adobe Photoshop CS' because Power PC applications are no longer supported."

We'd prefer not to strip the computer back to the previous operating system, Snow Leopard, in order to install Photoshop, then go through the rigmarole of upgrading to Mountain ion again, but what is to be done?

Hmm. Are you sure it's not Photoshop CS2? CS3 installs on 10.8 just fine for me.

(CS2 was PPC only. CS3 supports Intel)
