Hello! Well, I know that a lot of people have been having issues when trying to download the client from the website, and/or through Aeria Ignite. I struggled for hours myself just trying to get it to work so I could test something out. But I finally ran across a solution and got it to download properly. So I'm going to mention it here so others can try it also and see if it works for you as well.
First off, go to Control Panel, and find Akamai NetSession Interface Control Panel, if you have it. Then open it up.
Then once it's opened, go to the Preferences tab, and click "Stop" at the bottom if it shows the Service as "Running". If it shows it as Stopped already, you don't need to do anything.
Next, click on this link
and once it's downloaded, click on it to install it. Then once you finish installing that, then try to run your "edeneternal_us_downloader.exe" file again, and see if it then works properly.
Please reply in this thread and let me know if this works for you or not, thanks!
