For Windows, Steam, and PlayStation®4, the free trial client is not the same as the full version client, so it is necessary to uninstall all free trial clients before installing the full version client.

 - Windows Full Version Client: https://www.finalfantasyxiv.com/playersdownload/na/
 - Steam Full Version Client: Please download directly from your Steam Library.
 - PlayStation®4 Full Version Client: Please download the full version client from the PlayStation Store.

The PlayStation®5 and Mac free trial clients are the only clients that are the same as the full version. Once upgraded, simply log in to the same Square Enix account you were using the play the free trial.
