Office Update Language Error

[Tony-y]

User running Windows XP Pro in English and Office XP in
English, when updating OS and Office at
office.microsoft.com and windowsupdate.microsoft.com is
not able to obtain the Language Interface in English.
Instead, as user resides in Italy, gets the Italian
interface.
How to force the system or how to switch to English?
With windowsupdates.microsoft.com user is able to switch
through Other Languages. But, with Office, when user
selects another language, it still remains in Italia.

Thank you for your answer.
