错误代码:

Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works.
PSDispatch looks fine. Weird.

返回代码: E_NOINTERFACE (0x80004002) 
组件: VirtualBoxClientWrap 
界面: IVirtualBoxClient {d2937a8e-cb8d-4382-90ba-b7da78a74573}

解决办法：在注册表里面进行修改

HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}
InprocServer32 修改为C:\Windows\system32\oleaut32.dll

HKEY_CLASSES_ROOT\CLSID\{00020424-0000-0000-C000-000000000046}
InprocServer32 修改为C:\Windows\system32\oleaut32.dll
