Support for the older Office 2002 products has ended.. See the link below and it doesn't include Office 2002 items:
http://support.microsoft.com/kb/950929
Still, there is another MS article which lists phone numbers which might get it done for you..
http://support.microsoft.com/kb/326851
All you need is a cell phone to make the call with.. Of course, if MS refuses to support your older version, you may have no other choice than to purchase a newer version.
Hope this helps.

I just bought a new computer with Windows 7. I want to install Word 2002, which I like and use for my job every day and have the disk, but it's telling me that it can't connect to the Microsoft activation service through the internet. I don't have a phone line that I can use. I've tried reading about this on Microsoft's website, but I'm very computer illiterate and it's way over my head. Can someone explain to me what they mean about changing my proxy or what else I could try?
Thanks much.
