I wanted to read a docx file today but I don’t have any Office products (or equivalent installed) so the trick is to;
1. Install Word 2003 viewer (download from MS site)
2. Install Office 2007 compatibility kit (download from MS site)
3. Reboot (required for me so the docx extension was correctly registered

The next trick is that when I double click the document the converter from the compatibility kit kicks in but then the dumb thing launches WordPad instead of the 2003 viewer. So currently I’m forced to open the viewer first and browse to the docx.

I\’ve now set the default program for docx to be the Viewer so I can avoid the initial step of opening the viewer first.
