This is the #1 google result for this error so I'm just quickly posting the solution here even if the thread is a year old, this is because of a defective WMI database on the PC, you will have to delete it so Windows can re-create it from scratch (the WMI database just contains cached data about hardware and software information on the PC). You can use these instructions: hxxp://windowsxp.mvps.org/repairwmi.htm
