I am having a workstation in my network which has Microsoft Office 2003. While on other there is Office 2007. The pc is quiet old so we ignored upgrading to Office 2007 on the same. Now there is a central share location where all Excel and Word files are kept. After adding the new version of Office the file extension is changed to docx and xlsx. I want some help here to allow that old system to view this new files in Office 2003. Is that possible. I found a compatibility pack but somehow it is not working well.
