Earliest photoshop compatible with OSX (snow leopard) 64 bit system?

[Guest]

What is the earliest release of photoshop that will run on this system?

Thank you.

I was able to launch Photoshop CS4 and CS5 successfully.  We only offer CS6 for sale though currently which also will work fine on Snow Leopard.

Let's go back before CS. How about Photoshop 7?

Photoshop 7 was an OS 9 program, it won't work under Snow Leopard. According to the Wikipedia that last compatible version for Photoshop 7 was OS 10.1.
