Changing language of program in Office 2007

Hello group,

I am new to the Dell Forums and need help.

I have a Latitude D610 laptop, running Win.XP Home.

My problem is that my Office 2007 has been installed in french and when I went to change the language to english, I found out the service tool weren't installed so I went to Office updates and found that i could download a language pack for english. The problem I have is I don't know if I should download the service pack in french or english because my program is in french. My operating system is all english but just my Office 2007 is in french. I am really cofused as to which language pack to download. Could someone help me with my problem? Thank you very much for any help you can give me. Lee
