As per my previous post, the Microsoft Office 2010 Code Compatibility Inspector and Microsoft Office Environment Assessment Tool are now available for download from the web. Documentation for usage is here:

• Microsoft Office Environment Assessment Quick Start Guide
• Microsoft Office Environment Assessment User Guide
• Microsoft Office 2010 Code Compatibility User Guide

Additionally, the Office 2010 Compatibility Assessment and Remediation Guide is also available. These tools and documents are in BETA form until the full release of Office 2010 in the first half of next year, but you can still use them and provide feedback.
