Estou tendo um problema com meu aplicativo, no qual estou tentando obter todas as configurações de rede do sistema em que ele é executado. O objetivo final é encontrar o endereço MAC com a maior prioridade.

O código é executado ok e funciona quando eu o executo com QtCreator e também é executado quando eu crio uma pasta que contém os arquivos DLL e o arquivo exe.

Mas o problema é que, quando executo esse programa em outras máquinas Windows (7 e 10), ele é executado, mas não retorna nem mostra nada. Tentei executá-lo como um administrador, que não funcionou e esse código deve funcionar em todas as plataformas do Windows.

Alguma sugestão?

Estou atualmente noWindows 10 e usandoQt 5.8 MSVC 2015

O arquivo exe é executado com essas DLLs no Windows 10:

Qt5Core.dllQt5Network.dllmsvcp140.dllmsvcr120.dllvcruntime140.dll

Essas DLLs também devem estar lá para o Windows 7:

api-ms-win-core-file-l1-2-0.dllapi-ms-win-core-file-l2-1-0.dllapi-ms-win-core-localization-l1-2-0.dllapi-ms-win-core-processthreads-l1-1-1.dllapi-ms-win-core-string-l1-1-0.dllapi-ms-win-core-synch-l1-2-0.dllapi-ms-win-core-timezone-l1-1-0.dllapi-ms-win-crt-convert-l1-1-0.dllapi-ms-win-crt-environment-l1-1-0.dllapi-ms-win-crt-filesystem-l1-1-0.dllapi-ms-win-crt-heap-l1-1-0.dllapi-ms-win-crt-locale-l1-1-0.dllapi-ms-win-crt-math-l1-1-0.dllapi-ms-win-crt-multibyte-l1-1-0.dllapi-ms-win-crt-runtime-l1-1-0.dllapi-ms-win-crt-stdio-l1-1-0.dllapi-ms-win-crt-string-l1-1-0.dllapi-ms-win-crt-time-l1-1-0.dllapi-ms-win-crt-utility-l1-1-0.dll

O link abaixo é o arquivo exe e dll:

aqui está o meu código, se necessário:
