Recently lot of my friends are suffering from this dilemma that how to open Microsoft Office 2007 files (with formats like .xlsx, .docx, .pptx etc) and we use to convert files from Microsoft 2007 formats to Microsoft Older Versions, and this way of doing was little boring and time consuming, So i searched for a way to open, edit, modify and save Microsoft 2007 in Microsoft Office 2003, 2000.

See how simple now it is..

Just download this below linked Compatibility Pack from Microsoft itself, run it and thats all..

By installing the Compatibility Pack in addition to Microsoft Office 2000, Office XP, or Office 2003, you will be able to open, edit, and save files using the file formats in newer versions of Word, Excel, and PowerPoint . The Compatibility Pack can also be used in conjunction with the Microsoft Office Word Viewer 2003, Excel Viewer 2003, and PowerPoint Viewer 2003 to view files saved in these new formats. For more information about the Compatibility Pack, see 924074.
