I've got a Windows Server 2003 that originally had just SQL Server 2005 standard edition on it. Later I installed SQL Server 2008 standard edition on it as well. I am now trying to uninstall SQL Server 2005 and the uninstall is terminating with a fatal error. This server also runs Active Directory. Can't remember if I promoted it after the initial SQL Server 2005 or before. The specific error message: "The setup has encountered an unexpected error while Setting Internal Properties. The error is : Fatal error during installation." I came across this kb article, but my registry does not have the exact keys they specify so I could not do anything with it:
Thanks for any help.
