我的应用程序遇到问题，我试图获取它运行的系统的所有网络配置。最终目标是找到优先级最高的MAC地址。
当我使用 QtCreator 运行代码时，代码运行正常并且可以工作，当我创建包含 dll 文件和 exe 文件的文件夹时，代码也运行正常。
但问题是，当我在其他 Windows 计算机（7 和 10）上运行此程序时，它会运行但不会返回或显示任何内容。我尝试以管理员身份运行它，但这也不起作用，并且此代码应该能够在所有 Windows 平台上运行。
有什么建议么？
我目前正在Windows 10并使用Qt 5.8 MSVC 2015
该 exe 文件在 Windows 10 上与这些 dll 一起运行：
- Qt5Core.dll
- Qt5Network.dll
- msvcp140.dll
- msvcr120.dll
- vcruntime140.dll
对于 Windows 7，这些 dll 也应该存在：
- api-ms-win-core-file-l1-2-0.dll
- api-ms-win-core-file-l2-1-0.dll
- api-ms-win-core-localization-l1-2-0.dll
- api-ms-win-core-processthreads-l1-1-1.dll
- api-ms-win-core-string-l1-1-0.dll
- api-ms-win-core-synch-l1-2-0.dll
- api-ms-win-core-timezone-l1-1-0.dll
- api-ms-win-crt-convert-l1-1-0.dll
- api-ms-win-crt-environment-l1-1-0.dll
- api-ms-win-crt-filesystem-l1-1-0.dll
- api-ms-win-crt-heap-l1-1-0.dll
- api-ms-win-crt-locale-l1-1-0.dll
- api-ms-win-crt-math-l1-1-0.dll
- api-ms-win-crt-multibyte-l1-1-0.dll
- api-ms-win-crt-runtime-l1-1-0.dll
- api-ms-win-crt-stdio-l1-1-0.dll
- api-ms-win-crt-string-l1-1-0.dll
- api-ms-win-crt-time-l1-1-0.dll
- api-ms-win-crt-utility-l1-1-0.dll

如果需要，这是我的代码：
