Codeweavers is late in updating the CX rating. In fact, the Compatibility Pack is one of the installable applications on 7.1. Check the box that says Show All Dependencies....
I have it installed and running and have used it to open both doc and docx files that contain images and fancy formatting, including backgrounds and borders. I gave up on OpenOffice when it could not open one of the docx files with a background and a border. That is pretty simple. I teach so I need to see exactly what the students are submitting; therefore I am now totally committed to CX Office, and thank goodness for the Compatibility Pack. Office 2007 also runs so I have a choice.
