SQL Server 2014 Service Pack 1 has released – Updated

 Important Updates on 4/22:

Immediately following the removal, we started preparing a new SQL Server 2014 Service Pack 1. We have learned several things that we wanted to pass along as well as share what is happening currently:


  • In the 11 hours of availability, there were 270 downloads from the Download Center. No other distribution channels were affected.
  • The original release was version 12.0.4050.0, the new release will have a new KB and build number.
  • If you have already installed the original SP1 release (12.0.4050.0), you are welcome to use it. However, we do want to minimize the number of installs of 12.0.4050.0 for servicing reasons.
    • When SP1 is rereleased, we will recommend that 12.0.4050.0 be uninstalled prior to applying the new SP1 update. This includes any “Side by Side” instance scenarios.
  • We are targeting release in a few weeks and will share updates as we go.


Although the package was only briefly available on the Microsoft Download Center, we apologize for this mistake and the inconvenience you may have encountered as a result. We not only did a full root cause analysis, but have also taken additional measures to prevent this in the future. We remain fully committed to top quality SQL Server servicing deliverables going forward.


Thank You

Important Updates on 4/16:

Dear SQL Customers,

We have chosen to remove SQL Server 2014 Service Pack 1 (SP1) from the Microsoft Download Center due to a significant installation issue discovered shortly after release. We sincerely apologize for the inconvenience this has caused you.

We will fix the installation issue and release the Service Pack for production use in a few weeks. Although operationally equivalent, only the newly released SP1 will be serviced (security updates, cumulative updates, hotfixes). Therefore, it will be important that you replace the current version of SP1 (12.0.4050.0) with the upcoming one.

In the meantime, you can continue to test and use build 12.0.4050.0. If you are experiencing the issue below, please implement the steps described in the workaround section.

We will communicate further as we approach the release date and we appreciate your patience.

Issue summary:


Any SQL Server instance with SSISDB catalog enabled runs into the following installation error during SQL Server 2014 SP1 upgrade.  The instance is then in an invalid and unusable state.

Error: 912, Severity: 21, State: 2.

Script level upgrade for database ‘master’ failed because upgrade step ‘SSIS_hotfix_install.sql’ encountered error 3602, state 251, severity 25. This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the ‘master’ database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion.

Error: 3417, Severity: 21, State: 3.

Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online. SQL Server shutdown has been initiated


  1. In SQL Server Configuration Manager, click SQL Server Services.
  2. In the right pane, right-click SQL Server(InstanceName), and then click Properties.
  3. On the Startup Parameters tab, in the Specify a startup parameter box, type the parameter “-T902”, and then click Add.
  4. Click OK.
  5. Restart the Database Engine.
  6. Connect to SQL Server instance from SQL Server Management Studio and run the following script to resolve the errors causing script upgrade to fail. This will create a temp table.


    use master



CREATE TABLE [internal].[object_parameters]   


    [project_id] [bigint] NOTNULL,

    [project_version_lsn] [bigint] NOT NULL



        7. Remove the -T902 trace flag from SQL Server Configuration manager

        8. Restart SQL Server Instance.  SQL server SP1 will be installed correctly.

        9. Remove the temp table by the following script


use master


DROP TABLE [internal].[object_parameters]




Notice: The SQL SSIS team has found an issue with SP1 installation if SSIS catalog is present in the SQL Server instance.They are currently investigating this issue including possible workarounds and fixes. We have temporarily put the package download on hold and will provide an update with a solution.
