那些遇到过的问题

部署的 Qt 应用程序 QtWebEngineProcess 无法加载 Qt5Core.dll

joh*_*co3 3 c++ deployment qt

我需要帮助才能将 Qt 5.14.1 x64 应用程序正确部署到客户端的 Windows 10 PC。该应用程序使用QtWebEngineProcess在选项卡式界面窗口之一中显示谷歌地图。

这曾经工作正常，直到 Visual Studio 2019（当前最新版本 16.4.5）更新或 QT 版本从先前版本更新 - 我认为使用版本 5.13.2。我无法判断哪个更改导致了错误。

问题是当应用程序在客户端的 PC 上启动时（没有 Visual Studio 或 Qt）。当我双击该应用程序时，它会暂停几秒钟，最终弹出一个对话框，表明找不到 Qt5Core.dll。（与应用程序位于同一文件夹中），不久之后它会显示另一个对话框，错误代码为 0xc0000022。

它们与从我的主应用程序可执行文件 (app739.exe) 实例化的子进程 (QtWebEngineProcess.exe) 相关联。

将工作（之前的）版本与当前工作版本进行比较，我注意到存在一个新的 DLL 依赖项VCRUNTIME140_1.dll。这似乎与异常处理有关，但是 QtWebEngineProcess.exe 没有将此 dll 列为依赖项。

该应用程序的部署如下：

我使用 Qt 5.15 和 VS 2019 时遇到同样的问题。但是，仅当我的应用程序部署在网络驱动器上时才会出现此问题。相同的文件集合（其中 qt5Core.dll 位于同一文件夹中）在所有本地驱动器上都可以正常工作。
