Now you can translate your Microsoft Office documents with Microsoft Translator . You can even translate words, phrases, or even your entire document, through the Research task pane.
The Microsoft Translator Official Team Blog has blogged about setting up manually for Office 2007 and Office 2003 previously.
Microsoft Office 2003 and Microsoft Office 2007 currently use WorldLingo as the default machine translator in the Research task pane. This download will update the Research task pane registry keys to set Microsoft Translator as the default translator and WorldLingo as the fallback translator.
This works for both Microsoft Office 2003 and 2007. Download the Installer through following link.
