U don't have to buy a new version of Word! Just install this and U should be able to see any Word document! Then paste it into 97 and make changes there hopefully!
ivnj's link is to a MS Word Viewer program. An even easier way is to download and install the Microsoft Word Converter:
Converters enable you to open files created by people using different versions of your Office programs. Find the appropriate converter for the version of the Office program on your computer.
Viewers enable people who don't have Office programs to see your work. Simply provide them with the appropriate viewer along with your files.
