This has circulated well on various photo forums but is of interest to many here. Adobe has decided to give away the complete CS2 studio. This is an older version but still of some value.
The primary interest for many here is that it includes Acrobat 7.0 and Acrobat Pro 8.0. These are full licensed versions, though they do not qualify for any upgrade. Patches and fixes within the same major version will work. It also includes both Photoshop CS2 and Photoshop Elements (v4 for Mac and v5 for Win). There are downloads for the full CD set and individual installers for each app so if you don't want/need everything you can just down load what you want. Adobe's "system requirements" don't list many recent OS versions (none more recent than CS2 itself). Reports on the photo forums I frequent report success with newer Windows versions though there have been some installation issues with the full CD set (try the individual installers instead if necessary). I haven't read reports about newer MacOSX versions either way.
As you can imagine, there have been a lot of downloads and the servers' bandwidth has been a bit taxed at times. If this link fails then try again later.
