Using Office 2007 documents in all old versions of Office

Files in the new Office formats often cause problems when they are opened with older versions of the software. Yet not many prefer to buy the new Office package just to work in an “upwardly compatible” way.
You need not buy the new Office package. Microsoft has released the “Compatibility Pack” solely for this purpose. You can download it form the Microsoft Download Center. Please ensure that you have the latest versions of Office XP and 2003 and that all important updates have been installed before you install the tool.
To install the “Compatibility Pack”, start Windows Update or open the link “http://www.microsoft.com/downloads/thankyou.aspx?familyld=941b3470-3ae9-4aee-8f43-c6bb74cd1466&displayLang=en” in the browser and install the available updates. Then, open the “FileFormatConverters.exe” file and finish the installation process.
