Windows Management Instrumentation (WMI) is referenced in the error message.
This is a major component of the Windows operating system and it is possible for this installation to become corrupt or unusable.

There is a utility from Microsoft that can diagnose WMI problems. http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=7684.
Note: Running and diagnosing the results of this utility are outside of Blackbaud’s scope of support.
