I have a named instance of SQL Server 2005 Express SP3 that I am attempting to upgrade to SP4 using the following command line:
SETUP /qb UPGRADE=SQL_Engine INSTANCENAME=MUNISOFT
I am getting the following error: "The setup has encountered an unexpected error while Setting Internal Properties. The error is: Fatal error during installation."
I am able to create new named instances using the SP4 setup files, but I cannot upgrade the existing instance.
I am running Windows Server 2008 R2 on a 64 bit system.
