MKS Toolkit errors occur when removing clients

Only one version of the MKS Toolkit can exist on a Microsoft Windows computer at a time. The MKS Toolkit is installed with the IBM® InfoSphere® Information Server clients. If you install a newer version of the clients, the version of the MKS Toolkit that is packaged with the clients overwrites any older version of the MKS Toolkit on the system, resulting in version incompatibility issues between the MKS Toolkit and older versions of IBM InfoSphere Information Server clients. Version incompatibility might also cause problems when you remove older InfoSphere Information Server clients.

Symptoms

When you try to remove InfoSphere Information Server clients, you might see several possible symptoms that point to version incompatibility issues:
  • When you attempt to remove an older InfoSphere Information Server client, error messages are displayed when the software removal program tries to remove the MKS Toolkit. The messages are displayed because the older version of the InfoSphere Information Server client is not compatible with the new version of the MKS Toolkit.
    The following error message is displayed:
    ERROR: The product bean "installMksClientAction" could not be loaded...
  • At the end of the software removal of the older InfoSphere Information Server client, the following error message is displayed:
    Could not uninstall assembly: uid=mksinstaller : version = 8.0.0.0: instance = 1
  • After you remove IBM InfoSphere Information Server, Version 8.0.1 clients, the product shortcuts are not removed from the Windows Start menu.

Causes

A newer version of the MKS Toolkit was installed and overwrote the previously existing version that was installed by the InfoSphere Information Server client that you are trying to remove. If you install multiple versions of the InfoSphere Information Server client, the only version of the MKS Toolkit that remains on your computer is the version that is packaged with the newest version of the InfoSphere Information Server client that you install.

If you remove the version of the InfoSphere Information Server client that installed the current version of the MKS Toolkit without removing the MKS Toolkit, the remaining clients continue to run. However, if you later try to remove the remaining clients, you might receive error messages when you try to remove the MKS Toolkit because the versions are incompatible.

Environment

This advice applies to all Microsoft Windows operating systems.

Resolving the problem

If you removed all IBM InfoSphere DataStage® and InfoSphere Information Server clients but the MKS Toolkit remains, you can remove it by using the add or remove program function that is available with your version of Windows. Reboot the computer after removing the MKS Toolkit.
