I'm getting the same Installation Failed error as pictured above by redesign. It says download appears corrupted. Press Cancel, wait a few minutes and try again. (-60). I've done that and uninstalled and reinstalled the AAM and uninstalled the preview version of Edge with no luck. The download doesnt get past 1%. I'm working with my IT department to see if its a proxy issue but thought I'd post here in case there is a solution I havent come across.
Here is my update about the install - It appears that it was some network issue preventing the manager from downloading the necessary files. I believe they took the computer off the netword and were able to install Edge Animate. So I am not sure about the other users in this thread but if they still have the same issue, they could do the same and it should work.
