According to Adobe, these seemingly free downloads were/are available only for clients who had already purchased CS2 software:
What I mean?
Adobe is offering various software downloads for free - Photoshop CS2 among others!
Whoever wasn't able to afford them until now should take advantage.
You only need to register for free at the Adobe website. And probably need to set the programs to run in "Windows XP mode" if you're using a newer Windows.
I'm going to test a few of these right now! I have only Photoshop which I bought years ago, none of the others!
