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？
这是我在Windows下部署QOwnNotes （Qt5）的方法： https ： //github.com/pbek/QOwnNotes/blob/develop/appveyor.yml
