Add features to an existing instance

  • Hi I need to install Full search and Analysis services to an existing instance of SQL Server 2012. When I run set up or click change from the control panel, setup does not see that the SQL instance is out there.

    What does it use to find existing instances to upgrade? Is it a registry entry or some sort of scan? I recently applied some hardening changes to the instance from a CIS benchmark so I don't know if that has anything to do with it.

    Any ideas how to get setup to see the instance?

  • Still stuck on this one. How does the SQL Server installer detect existing instances to add features? How can I get analysis services added to an existing instance if the installer does not detect the instance?

    Anyone have experience?

  • I think the SQL Server Setup looks at the windows registry to check for existing instances, something like the below.

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names

  • Thanks.

    They instances are listed there but SQL Server install does not see either one. I'm just going to go a clean install then move the databases into the new instance.
