Where and how can I download Adobe CS 5.5 and its licence? I can't seem to find it anymore? They only option Adobe forces on me is CS 6.
Your best bet would be to contact Adobe directly. If you already have a license for CS5.5 they should be able to provide you with installation media.
If on the other hand you are wanting to buy CS5.5, then you may well be out of luck, as i think they are only selling 6 and above (creative cloud) now.
