VBSCLASSBROWSER.HTM README In order to run the VBCLASSBROWSER sample you must first ensure that the WMI Class Navigator and WMI Login ActiveX controls are installed on your system. Failure to ensure this will result in the sample being unable to load the controls, and they will not appear on the page. To install the WMI controls, run one of the WMI SDK tools (for example, CIM Studio).
