How to Open Word 2007's DOCX Files
Jarte can open DOCX files (aka, Open XML or WordProcessingML files) created by the Microsoft's Word word processor if Word is installed on the same computer or if Microsoft's Office Compatibility Pack is installed on the computer.
The Office Compatibility Pack can be downloaded free of charge from Microsoft's web site. Close and restart Jarte after you have installed the Office Compatibility Pack and Jarte will then be able to open DOCX files.

Note that at this time Jarte is unable to save files using the DOCX format. Any changes made to a DOCX file can only be saved by saving the file as a DOC or RTF file.
