Melbourne Park. I know, for certain, that Photoshop CS6 installer can be downloaded (see previous posts, in this thread), if you have lost your own installer disc. If you particularly want to use P.S. and you bought it from Adobe, there will be a serial number stored in your account — there is in my account. As I see it, there are a lot of hoops to jump through, but if you are attentive, you will be able to install it. Read the previous posts. Good luck!Clod Hopper - I'm a bit like you. Rarely used Photoshop. But sometimes I need it. I did the art work for the name of my yacht. The Pros job was horrible. I too have a 2010 Mac Pro.
I lost something and went to re-install. And couldn't find my disk!! I had lots of software discs. Even Quark Express. Various versions of Illustrator. But no actual disk, and the box I have didn't have the numbers on it. I think they were inside a secondary box. I range Adobe and my account didn't register
In the end I went for the rental version.
I reckon my CS6 is available on a backup. But I gave up.
I paid for the alternative to Photoshop too ... but its interface was very different, and i gave up pretty quickly.
C.H.
PS: I would think it is a waste of time to ring Adobe. Look for your account on-line. I presume you know your password? Even if not, if you remember the registered email and can enter that, they will allow you to set a new password.
