SYMPTOMS

When you try to install or to remove the Microsoft Shared Computer Toolkit for Microsoft Windows XP, you experience the following symptoms:

• When you try to install the toolkit, you receive the following error message:

  This installation requires Windows Management Instrumentation (WMI). Review the following Knowledge Base article 905287 to learn how to repair or reinstall WMI. Installation aborted.

  If this error occurs, the installer program quits. You must reinstall WMI before you can install the toolkit. To do this, perform the "Reinstall Windows Management Instrumentation" procedure that is described in the "Resolution" section.
• When you try to remove the toolkit, you receive the following error message:

  Review the following Knowledge Base article 905287 to learn how to repair or reinstall WMI and finish uninstalling the toolkit. Uninstall will continue.

  If this error occurs, let the process finish removing the toolkit. Reinstall WMI, and then perform the "Uninstall cleanup" procedure that is described in the "Resolution" section.

CAUSE

These problems occur if WMI is missing or damaged.

RESOLUTION

To resolve the error that occurs when you try to remove the toolkit, let the program finish removing the toolkit. Next, perform the "Reinstall Windows Management Instrumentation" procedure, and then perform the "Uninstall cleanup" procedure.

Reinstall Windows Management Instrumentation

To resolve the error that occurs during installation, you must perform an in-place upgrade (reinstallation) of Windows XP. For more information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:

Uninstall cleanup

1. Click Start, click Run, type control schedtasks, and then click OK.
2. Select all three of the tasks that were created by the Windows Disk Protection tool. These tasks are typically named At1, At2, and At3.
3. Press DELETE, and then click YES to confirm the deletion.
