When the latest round of updates came through my computer would not take the update but simply say "error" after it was finished downloading. However AE would start and work it just did not have the update. Out of frustration I uninstalled then tried to reinstall the program. I could not get AE to install at all.
I checked the forums and people suggested using the Adobe cleaner. I followed the procedure but still AE would not install but others like Premiere Pro installed fine. I am attaching screen shots of my operating system and the error messages. Thank you!
What did you get when you clicked on "More information"?
