Just when she was about to throw in the towel, Emma stumbled upon a forum post from a fellow designer who had encountered the same issue. The solution was buried in a lengthy thread, but essentially, it involved deleting a specific registry key and then reinstalling Illustrator.
With trembling fingers, Emma navigated to the registry editor and deleted the offending key. She then reinstalled Illustrator, holding her breath as the software activated without a hitch. The Amtlib.dll error was gone, and Emma was back in business.
