I have a new laptop and it windows 7 I am in Word and trying to attach my document to an email which I did but it won't open when the reciever tries to open it.
If you sent it as a .docx file, the email recipient will either need Office 2007, or the Office 2007 Compatibility pack if they are using Office 2003.
you can download this from microsoft, just search it in google.
or you can save it as a 2003-word file (drop-down menu(the big round button on the top-left corner) and save as ...(old-version/ 2003-version/...)
