Microsoft introduced a new file format called the Microsoft Open Office XML Format (.docx) in the Office 2007. It can be a real problem since the format is not backwards compatible. You cannot open and print the .docx file, if you don’t have Office 2007 and above.

Convert .docx to .doc

To solve this problem you need to download the free Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats. This will help you to open, edit, and save files using the file formats in newer versions of Word, Excel, and PowerPoint.

Alternatively, if you don’t want to install the Microsoft Office Compatibility Pack, you can convert .docx file by using the free online .docx to .doc converter service.
