无法find或加载Qt平台插件“窗口”

首先,为了防止重复的报告,我尝试了多种解决scheme, 在这里 , 在这里 , 这里和这里 。

我在Visual Studio 2012中使用Qt 5.5.1,并在Windows 10 x64(不使用Qt Creator)上开发我的应用程序。 应用程序在发布模式下编译。

其实,我的应用程序正在我的电脑上工作 ,没有任何问题,我需要在我的目录中唯一的库是:

Qt5Core.dll Qt5Gui.dll Qt5WinExtras.dll Qt5Widgets.dll Qt5Network.dll msvcp110.dll msvcr110.dll 

现在,当我试图启动我的应用程序全新安装的Windows 7 x86时,我收到以下错误信息:

此应用程序无法启动,因为它无法find或加载Qt平台插件“窗口”。

重新安装应用程序可能会解决此问题。

现在我无法摆脱它。 根据以前提出的问题,这可能是qwindows.dll文件(或更确切地说,应用程序无法find它)的问题,首先,我做了我的发布目录的部署,如下所示:

[..]\msvc2012\bin>windeployqt.exe <PATH>

它已经生成了我的应用程序启动所需的所有文件,包括platforms/qwindows.dll因此我只是简单地将它们全部复制到Windows 7目录而没有任何影响 – 仍然会出现错误。

我也尝试从msvc2012\plugins\platforms手动复制一个qwindows.dll – 没有效果,

我做的最后一步是在Dependency Walker中检查我的应用程序 – qwindows.dll是,没有qwindows.dll相关的依赖关系:

所以我现在没有想法,这里有什么问题?
