IVssBackupComponents::InitializeForBackup fails

ivssbackupcomponents :: initizeizeforbackup失败，而e_unepped错误。如果查看器有两个错误：

错误1

Volume Shadow Copy Service error: A critical component required by
    the Volume Shadow Copy service is not registered. This might
    happened if an error occurred during Windows setup or during
    installation of a Shadow Copy provider. 
   The error returned from
        CoCreateInstance on class with CLSID
        {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and Name IVssCoordinatorEx2
        is [0x80040154, Class not registered ].
    Operation:
       Instantiating VSS server

错误2

Volume Shadow Copy Service error: Unexpected error calling routine
    CoCreateInstance.  hr = 0x80040154, Class not registered.
    Operation:
      Instantiating VSS server

我创建了简单的" Hello World" VSS程序：

#include "vss.h"
#include "vswriter.h"
#include <VsBackup.h>
#include <stdio.h>
int main()
{
#define CHECK_PRINT(result) printf("%s %#08xn",result==S_OK?"S_OK":"error", result)
  HRESULT  result = CoInitialize(NULL);
  CHECK_PRINT(result);
  IVssBackupComponents *VssHandle;
  result = CreateVssBackupComponents(&VssHandle);
  CHECK_PRINT(result);
  result = VssHandle->InitializeForBackup();
  CHECK_PRINT(result);
  return 0;
}

它报告了相同的输出S_OK 00000000S_OK 00000000错误0x80042302

在我的主要开发Windows 10 PC和虚拟Windows10上，带有干净的安装。VSS，SWPRV服务正在运行。
