Hello, How are you doing? I would like to ask a question. which is that for office 2010 installation windows 7 and latest operating systems are required to be installed. It can't be installed in windows xp. any how when a person would like to share a file of ms word 2010 after saving as in version office 97-2003, then an other person who is operating windows xp and operating ms office 2003 then when he received the file it is not opening in office 2010.
