Manually removing InfoSphere Information Server from the engine tier (Windows)

If you cannot remove suite software by using the software removal program, then you must manually remove files and directories from the engine tier computer to ensure that the product is completely removed. Completely removing these files and directories is important if you plan to reinstall the suite.


  1. Back up the computer.
  2. Open an elevated command window:
    1. Click Start > Search.
    2. In the Search Results box, enter cmd and press Ctrl+Shift+Enter.
    3. Click Continue to accept the prompt asking for your permission to continue.
  3. If you previously installed older versions of IBM® InfoSphere® DataStage® or InfoSphere Information Server clients, Windows registry keys might remain on the system after you uninstall the clients. If you have uninstalled all InfoSphere DataStage or InfoSphere Information Server software, delete the following registry keys:
    Depending on the version of software you have installed, only some of the following keys might exist.
    HKEY_CURRENT_USER\Software\Wow6432Node\Ascential Software
    HKLM\SOFTWARE\Ascential Software\ASBNode
    HKLM\SOFTWARE\Ascential Software\DataStage Client
    HKLM\SOFTWARE\Ascential Software\DataStage Multi-Client Manager
    HKLM\SOFTWARE\Ascential Software\Documentation Tool
    HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Ascential Software
  4. Run the following commands to stop InfoSphere Information Server services:
    sc stop ASBAgent
    sc stop DSEngine
    sc stop dsrpc
    sc stop dstelnet
    sc stop IBMAPWSrv
    To stop InfoSphere DataStage Flow Designer, run the stopCognitiveDesignerServer.bat script, which is located in the following default directory: C:\IBM\InformationServer\ASBNode\CognitiveDesignerEngine.
  5. Run the following commands to remove InfoSphere Information Server services:
    sc delete ASBAgent
    sc delete DSEngine
    sc delete dsrpc
    sc delete dstelnet
    sc delete IBMAPWSrv
  6. The installation program uses a particular version of the MKS Toolkit on the client and engine tiers. If you did not first install your own supported version of MKS Toolkit, use Add or Remove Programs to remove the MKS Toolkit that was installed by the InfoSphere Information Server installation program.
  7. Delete the following path in the system environment path: <IS_INSTALL>
  8. Delete the InfoSphere Information Server installation directory.
    The default directory is C:\IBM\InformationServer\.
  9. If only the most recent version of the clients are installed on this computer, back up your registry and then delete the \HKEY_LOCAL_MACHINE\SOFTWARE\Ascential Software and \HKEY_LOCAL_MACHINE\SOFTWARE\IBM\InformationServer registry keys.
  10. Delete the following temporary directories that contain log files for the installation program.
    Note: If you chose a different directory for the temporary files, delete that directory instead of the default directories.
  11. Delete the Windows Start menu shortcuts from the following directories:
    C:\Documents and Settings\All Users\Start Menu\Programs\
      IBM InfoSphere Information Server\
    C:\ProgramData\Microsoft\Windows\Start Menu
    %ALLUSERSPROFILE%\Start Menu\Programs\IBM InfoSphere Information Server\
  12. Remove any remaining InfoSphere Information Server users and groups if you are not using them for other purposes.
  13. Restart each computer after you remove the suite.
    Microsoft Windows might not be able to remove some files and services until the computer is restarted.
    Attention: Do not perform a new product installation before restarting each computer. If you reinstall the product before restarting your computer, the new installation might fail.
