I have Word 2002 and 2013 installed. My client has Word 2013. I work exclusively in 2002 because it's a better program.

The file is originally in 2002. I need for my client to be able to view it in 2002 so that he can use Track Changes in 2002.

He can open the document in 2013, but the editing and comments don't display properly. I want to work with him in 2002 because it's a simpler program.

How can he view the document in 2002? Does he need to install a Compatibility Pack?
