Office 2007 installation problem

[teymour]

I try to install office 2007 enterprise and I get the message "the language
of this installation package is not supported by your computer"
I uninstall office 2003 (Farsi) completely and I have windows XP sp2 and and
I set Regional setting to English(US).
