问题描述

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 在其中一个选项卡式界面窗口中显示Google地图。

I need help to correctly deploy a Qt 5.14.1 x64 application to a client's Windows 10 PC. The application uses the QtWebEngineProcess to display a google map in one of the tabbed interface windows.

很好，直到更新了Visual Studio 2019（当前最新版本为16.4.5）或从先前版本更新了QT版本-我认为使用的是5.13.2版本。我无法确定是哪个更改导致了错误。

This used to work fine until either the Visual Studio 2019 (currently at the latest Version 16.4.5) was updated or the Version of QT was updated from the prior version - I think that used version 5.13.2. I cannot tell which change caused the error.

问题在于，当应用程序在客户端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，最终会弹出一个对话框，指示找不到Qt5Core.dll。 （与应用程序位于同一文件夹中），此后不久，它显示另一个对话框，错误代码为0xc0000022。

The problem is that when the application launches on the client's PC (without Visual Studio or Qt). When I double click on the application, it pauses for a few seconds and eventually it pops up a dialog indicating that it could not find Qt5Core.dll. (which is in the same folder as the application) and shortly thereafter it shows another dialog with error code 0xc0000022.

这些与子进程（QtWebEngineProcess.exe）相关联从我的主应用程序可执行文件（app739.exe）实例化。

These are associated with a child process (QtWebEngineProcess.exe) that gets instantiated from my main application executable (app739.exe).

将工作（先前）版本与当前工作版本进行比较，我注意到 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。

Comparing the working (prior) version to the current working version, I noticed that there was a new DLL dependency on VCRUNTIME140_1.dll. This seems to have something to do with exception handling, however the QtWebEngineProcess.exe does not have this dll listed as a dependency.

应用程序的部署如下：

推荐答案

使用Qt 5.15和VS 2019时我遇到相同的问题。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。同一文件集合（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。

I have the same issue using Qt 5.15 and VS 2019. However, the problem only occurs when my application is deployed on a network drive. The same collection of files, where qt5Core.dll is in the same folder, works fine on all local drives.
