download and make use of one of Microsoft's file viewers:
Alternatively if you download and install OpenOffice
( http://www.openoffice.org/ ) or 602Pro PC Suite ( http://www.software602.com/press/press45.html ) both of which are MS Office 2003 compatible to a degree (although formatting, macros, scripting, and embedding can present some potential problems for a few users).
I am trying to open files from Office 2003, such as word 2003, excel 2003 etc. But i get an error saying that my operating system is not currently configured to run this application. Is there any way i can configure my OS to make the files work?
