问题：
ailed 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}
解决方法：
修改注册表 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
