Latest zipped client available here, January 2013.
To avoid confusion, previous versions are no longer available.
Just unzip the client and run the launcher.exe to start the game.
If you experience any issues trying to unzip please download 7-zip and try unzipping again. I compressed with 7-zip so it should provide the appropriate compatibility.
For those wanting an old installer from Aeria without Ignite attached to it Eden Eternal installer, December 5, 2011 (No Aeria Ignite)
If you prefer using torrents to download things, you can grab the December 5, 2011 installer torrent here.
