I just installed VirtualBox 4.2.12 on a new PC running Windows 7 SP1. I downloaded and attempted to install the latest VirtualKD and encountered the following error:

Unable to cast COM object of type ‘VirtualBox.VirtualBoxclass’ to interface type VirtualBox.IVirtualBox’. The operation failed because the QueryInterface call on the COM component for the interface is IID ‘{uuid here}’ failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Does anyone know of a work-around for this problem? If I get past the install error, will VirtualKD work with Vbox 4.2.12?

Thank you,

David Schwartz
