I am trying to install SQL 2008 SBS on a 2008 server. The installation fails during the "Installation Rules" section due to SQL Server 2005 Express Tools. I am sure that SQL was either installed for either Trend Micro Worry Free Security and/or Acronis. I think both of those software packages use SQL Express. I do not want to uninstall SQL Server Express 2005 if that is going to have adverse effects on either of those installed programs. Does anyone know a way around this. Can i just uninstall the 2005 Tools and nothing else?
