Axure RP can generate specifications in Microsoft Word format.
The default specification generator creates Word 2007 (.docx) files. You do not need Word 2007 installed to generate or view .docx files.
The Microsoft Office Compatibility Pack enables Word 2000, XP, or 2003 to open, edit, and save Word 2007 files. It is installed with Axure RP if you do not have Word 2007 installed.
The Word 2000 generator used in Axure RP Pro 4 and earlier is also available. It requires Word 2000 or above to be installed.
To create a Word 2000 configuration click Generate->More Generators and Configurations in the main menu.
The specification includes screenshots of your wireframes and documentation of the pages and widgets.
