Today, I was reluctantly tasked with upgrading my 4-week old laptop to Office 2007 Enterprise Edition. My brand new HP laptop has Vista on it. After un-installing Groove and starting the install, the following error message pops up:

"Upgrade to the latest retail version of Windows Vista - The Problem was caused by Windows Vista, which was created by Microsoft Corporation. You are running a beta version of Windows Vista, which is no longer supported by Microsoft Corporation"
