Cannot pass COM object of type 'System .__ ComObject' to interface type '\ a. \ A ".
This operation failed because the call to QueryInterface for the COM component for the interface → with IID interface {39C13A4D-011E-11D0-9675-0020AFD8ADB3} failed:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA).
Anyone have an idea about this exception?
The likely reason is that the COM server started in a separate process and crashed when a call QueryInterface()requested an unsupported interface. If in this case it must be addressed by the COM server provider.
