Applying SP 4 to SQL Server 2000 I run the following command:

setup sapwd="<password>" instancename="local" targetdir="C:\Program
Files\Microsoft SQL Server"

and get the following error:

Windows XP Setup: Please go to the Control Panel to install and
configure system components

No log file gets created - the error happens after just a couple of
seconds. I get it whether or not SQL's services are shut down. There
are no other applications running. I've also tried giving it the
machine name for instancename (as displayed in the Enterprise Manager
tree). What am I doing wrong?

Thanks

Andy
