I have the same problem, message
RAD Studio Problem loading data Error on loading data from the server getit12new.embarcadero.com: Internal Server Error
It seems to me that the problem is not that the server is not working, but that the server (getit12new.embarcadero.com) no longer exists in the list of servers on the link

The question is where can I change the GetIt Package server address in an existing installation and in the installation program?
