有问题的申请是使用Qt 5.7和VS2015编写的。上周出现了一个奇怪的问题，我拼命想要解决这个问题。我认为有足够的日志记录，但看起来不像。然后再次出现这个问题只能在用户的几台机器上看到。
我们已确保部署在所有Windows计算机上运行良好，并且应用程序在上周在这些计算机上运行良好。现在它拒绝打开但是显示在任务栏中。
用户的计算机已安装必备软件，即VC ++ 2015.还存在所有必需的Qt DLL。该应用程序在其他所有计算机上都没有任何打嗝。所以我假设问题出在机器上，但是，重新启动2 OS（Windows 7和Windows 2012），干净地重新安装应用程序，不同版本都失败并显示相同的问题。
我现在的问题是
我使用windeployqt获取所有依赖项，同时测试找出了必要的其余DLL，如VC ++ 2015.同时构建使用dependecy walker。 很少有像qt application does not start和qt application launch issues这样的问题都指向缺少DLL。我知道情况并非如此，因为应用程序几乎在所有Windows机器上都能正常工作。所以我需要帮助和方向来记录依赖项以及如何诊断这种情况。
如果租约让我知道，我可能错过了一些信息。我正在研究更多，我将更新帖子，因为我得到了一些额外的信息。
还尝试在main（）函数中添加大量日志记录。看看我能抓到什么东西。
