迁移到X64后：CComPtr CoCreateInstance失败，未注册rc = 0x80040154类

IDL文件未更改

//import "objidl.idl";
//import "ICmConnection.idl";
//import "ICmNamedObject.idl";
//import "ipositio.idl";
//import "oaidl.idl";
//import "ocidl.idl";
import "objidl.idl";
import "ICmConnection.idl";
import "ICmNamedObject.idl";
import "ipositio.idl";


[ 
  uuid (96c64c60-24f6-99d0-9f8c-0020af9099cc),
  //uuid (E2123FC4-0D5D-4A8F-94BC-6582D9F84109),
  object, 
  pointer_default(unique)
]
interface ICMTopologieDatabase : IUnknown  /*IDispatch */{
  HRESULT GetObjects      ( [in] unsigned classID, [out] ICMPosition** devices   );
  HRESULT NewObject       ( [in] unsigned classID, [out] ICmNamedObject** device );
  HRESULT getNamedDevice2 ( [in] LPSTR name      , [out] ICmNamedObject** device );
  HRESULT InitializeClient();
}

我为MIDL编译器选项/ env x64 / x64（对于X64）提供了帮助
当我在寡妇注册表中检查uuid 96c64c60-24f6-99d0-9f8c-0020af9099cc时，根本找不到。

当我检查MIDL Complier生成的文件时，我看到可能不是，这可能是不正确的切换到X64

/* Compiler settings for D:\Home\Atiras\V77Ma_64Bit_Branch001\Src\Cm\NmsCmCommon\ITopolog.idl:
    Oicf, W1, Zp8, env=Win64 (32b run), target_arch=AMD64 8.00.0603 
    protocol : dce , ms_ext, c_ext, robust
    error checks: none
    VC __declspec() decoration level: 
         __declspec(uuid()), __declspec(selectany), __declspec(novtable)
         DECLSPEC_UUID(), MIDL_INTERFACE()
*/

是否可以通过此MIDL编译器设置不创建任何注册表，不注册类以及正确的开关是什么？
