Why can’t devices be added after installing TIA Portal V14? The CPU of the devices or other devices are shown with an exclamation mark, and the add button is grayed out. After authorizing the folder to open and install the long key, the key folder that was installed turns out to be empty.
What about humans? A kind person, please answer.
