I'm on Windows XP and I see a "RUNDLL" error pop-up when upgrading my client.

Players using Windows XP will get an error message pop up during the upgrade process. This should not prevent the upgrade from completing successfully. If you’re running XP and see this error message, feel free to close it out and proceed to enjoying the updated client. Note that you will see this error message a total of three times when running the updated client on Windows XP.
