Creative Suite archive
If you purchased Creative Suite 5, 5.5, or 6 from Adobe or registered your app, you may be able to download the installer for your app from your account.
Where can I download my Creative Suite app?
Creative Suite 5, 5.5, and 6
Creative Suite 2, 3, and 4
You can no longer reinstall Creative Suite 2, 3 or 4 even if you have the original installation disks. The aging activation servers for those apps had to be retired.
