Hi Carol,
Are you installing just the Outlook 2007 Business Contact Manager Add-in from CD#2?
Have you already run Outlook 2007 successfully after installing CD#1 and have you restarted the PC?
Are you logged in as Administrator?
BCM installs SQL Server express if there isn't another SQL database present and in some cases troubleshooting what is causing it can
get a bit tricky.
==================
Thanks for response. The error reads.....failed to install the required
component MS SQL Server 2005 express. Any ideas
