A friend of mine is telling me he can't download an attached Word doc from an email. He also said that 'a friend' had installed Word on his PC. Could it be that because he didn't get Word through legal channels that he's missing something. And no, 'a friend' is not myself.
may be that your freind has 2003 office and the attached file is the ne office 2007 tell him to go to microsoft download centre and download the office patch should be on main page at number 1: Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats then get him to try again and it should work
