Received the news that Microsoft Office 2010 Technical Preview this past weekend. This was certainly a cause for some excitement, proceeded to remove Office 2007 to prevent any installation failures. Unfortunately, the installation did not succeed; since a clean install did not work attempted an upgrade which also failed.
After a few hours of trying to make it work, recurred to move back to Office 2007.
In spite of these problems, still looking forward to installing and working with it as soon as this problem is fixed.
