Trouble with “ .DOCX” documents ?
We often get asked the question about how to open Microsoft Word “.DOCX” and Microsoft Excel “.XLSX” documents. Someone has sent you what you expect to be a standard Word document, yet it’s got a funny ‘.docx’ extension and your version of Word doesn’t recognise it.

These types of documents are created from Microsoft Word 2007 and have been saved as a new “Open XML” format so if you have an earlier version of Word then this is why your system doesn’t recognise it.
All you need to do is install a Microsoft Compatibility Pack for Word, Excel & PowerPoint 2007 file formats which you can download from here.
1. Click on the Download button.
2. Click on Save File.
