Qt platform plugin windows ошибка как исправить windows 10

I got this exact error on linux.

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. 
Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted (core dumped)

First, defining this environment variable before starting qtcreator causes more debug to be printed out:

export QT_DEBUG_PLUGINS=1

And then in the debug it said this when trying to start qtcreator from the commandline on ubuntu 18.04:

Cannot load library /home/myuser/Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so: (libxkbcommon-x11.so.0: cannot open shared object file: No such file or directory)

Note that it cannot find libxkbcommon-x11, so the fix was this:

sudo apt-get install libxkbcommon-x11-dev
export PATH=$PATH:~/Qt/Tools/QtCreator/bin

Now qtcreator starts.

Question

Issue: How to fix «Application failed to start because no Qt platform plugin could be initialized» error in Windows?

Hello. Recently, after a Windows update, I was unable to get OneDrive to work. Whenever my PC boots, I receive an error “Application failed to start because no Qt platform plugin could be initialized.” Any advice on how to deal with this issue? Thanks in advance.

Solved Answer

Windows operating system consists of many components – some are already pre-installed while others need to be implemented manually. For example, Node.js is one of the third-party components you would see on almost any Windows computer.

Qt is a C++-based^[1] framework that is designed to create applications on Windows, Android, Linux,^[2] and other platforms. While it is not a programming language on its own, apps that are based on it need to have the framework installed on their machines to be able to run. Unfortunately, these dependencies can create certain issues due to one reason or another.

When something goes wrong with the Qt platform, users may receive the “Application failed to start because no Qt platform plugin could be initialized” error.

Several applications could be affected by this error, including games such as Apex Legends,^[3] standalone components (Dllhost), or commonly-used apps as OneDrive. The latter resides in every Windows computer and is an extremely useful app commonly used for system/file backups or additional storage for user files.

Here’s the full message that users receive upon encountering the error (the error message text may vary in some instances):

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, windows.

While it may seem like enabling or installing the Qt platform would fix the “Application failed to start because no Qt platform plugin could be initialized” error, it is not the case. Reinstalling the app that is having difficulties detecting the plugin might help, however.

Unfortunately, that is not always possible, as users reported that they then received the “Can’t be found” error while trying to do so. The reason for this being is that a newer version of the app may be already present on the device, hence uninstallation is not possible. There is a way around it.

In some cases, the reasons for the error could be unrelated to the ones mentioned above. For example, system file corruption might also cause this error, so we recommend you try running a scan with FortectMac Washing Machine X9 repair software that could fix underlying Windows issues automatically. Otherwise, proceed with the below methods that should help you solve this error for good.

Method 1. Copy relevant folder to a different location

Method 2. Check system files for damage

• Type in cmd in Windows search
• Right-click on Command Prompt and select Run as administrator
• Here, type sfc /scannow and press Enter

  

• Wait till the scan completes and restart your machine
• If the SFC has returned an error saying it was unable to repair damaged files, run the following commands, pressing Enter each time:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth

Method 3. Try Clean Boot

• Type msconfig in Windows search, hit Enter
• Go to Services tab
• Check the Hide all Microsoft services checkbox and select Disable all
• Go to Startup tab and pick Open Task Manager
• Here, right-click on every entry and select Disable and close the Task Manager
• Go to Boot tab, tick Safe Boot and select Apply + OK.

  

Once booted back into Windows, try running the app you were having problems with. If that fixes your problem, it means that there is a third-party application that is at fault. In order to fix the “Application failed to start because no Qt platform plugin could be initialized” error, you should uninstall all recently installed applications and see if that solves your problem in normal mode.

Method 4. Reinstall the application in question

You should try uninstalling the app you are having troubles with and then installing it anew. If you are dealing with OneDrive, you should do the following:

• Press Win + R on your keyboard
• In the Run dialog, copy and paste the following:
  %userprofile%AppDataLocalMicrosoftOneDriveUpdateOneDriveSetup.exe
• Go through the installation steps and restart your PC

  

• If Windows can’t find the file specified, you should download the setup file from the official website [direct link].

If this method does not work and you are presented with an error, proceed with the method below and then repeat this step.

Method 5. Uninstall the problematic app via Command Prompt

Uninstalling a program that does not want to uninstall might be difficult, although it is possible via PowerShell, as you can launch it as an administrator. Keep in mind that the below example is for the OneDrive application, and the command would differ depending on the app name and its location.

• Open Command Prompt as administrator as explained above
• Copy and paste the following commands, pressing Enter after each:
  taskkill /f /im OneDrive.exe
  %SystemRoot%SysWOW64OneDriveSetup.exe /uninstall

  

• Note: if you are using 32-bit Windows system use the following command to uninstall OneDrive instead:
  %SystemRoot%System32OneDriveSetup.exe /uninstall
• This should force-uninstall the app.

Вопрос

Проблема: как исправить ошибку «Не удалось запустить приложение из-за того, что не удалось инициализировать подключаемый модуль платформы Qt» в Windows?

Привет. Недавно после обновления Windows мне не удалось заставить OneDrive работать. Каждый раз, когда мой компьютер загружается, я получаю сообщение об ошибке «Не удалось запустить приложение, потому что не удалось инициализировать подключаемый модуль платформы Qt». Есть какие-нибудь советы, как решить эту проблему? Заранее спасибо.

Решенный ответ

Операционная система Windows состоит из множества компонентов — некоторые из них уже предустановлены, а другие необходимо реализовать вручную. Например, Node.js является одним из сторонних компонентов, которые вы можете увидеть практически на любом компьютере с Windows.

Qt основан на C ++^[1] фреймворк, предназначенный для создания приложений на Windows, Android, Linux,^[2] и другие платформы. Хотя это не язык программирования сам по себе, приложения, основанные на нем, должны иметь установленную платформу на своих машинах, чтобы иметь возможность работать. К сожалению, эти зависимости могут создавать определенные проблемы по той или иной причине.

Когда что-то пойдет не так с платформой Qt, пользователи могут получить сообщение об ошибке «Не удалось запустить приложение, потому что не удалось инициализировать подключаемый модуль платформы Qt».

Эта ошибка может затронуть несколько приложений, включая такие игры, как Apex Legends,^[3] автономные компоненты (Dllhost) или часто используемые приложения, такие как OneDrive. Последний находится на каждом компьютере с Windows и является чрезвычайно полезным приложением, обычно используемым для резервного копирования системы / файлов или дополнительного хранилища для пользовательских файлов.

Вот полное сообщение, которое пользователи получают при обнаружении ошибки (текст сообщения об ошибке может отличаться в некоторых случаях):

Это приложение не удалось запустить, потому что не удалось инициализировать подключаемый модуль платформы Qt. Переустановка приложения может решить проблему.

Доступные плагины платформы: минимальные, закадровые, окна.

Хотя может показаться, что включение или установка платформы Qt исправит ошибку «Не удалось запустить приложение, потому что не удалось инициализировать подключаемый модуль платформы Qt», это не так. Однако переустановка приложения, у которого возникают проблемы с обнаружением плагина, может помочь.

К сожалению, это не всегда возможно, поскольку пользователи сообщали, что при попытке сделать это они получили ошибку «Не удается найти». Причина этого в том, что более новая версия приложения может уже присутствовать на устройстве, поэтому удаление невозможно. Есть способ обойти это.

В некоторых случаях причины ошибки могут быть не связаны с упомянутыми выше. Например, повреждение системного файла также может вызвать эту ошибку, поэтому мы рекомендуем попробовать запустить сканирование с помощью ReimageСтиральная машина Mac X9 программное обеспечение для ремонта, которое может автоматически устранять основные проблемы Windows. В противном случае используйте следующие методы, которые должны помочь вам навсегда решить эту ошибку.

Способ 1. Скопируйте соответствующую папку в другое место

Способ 2. Проверить системные файлы на наличие повреждений

• Введите cmd в поиске Windows
• Щелкните правой кнопкой мыши на Командная строка и выберите Запустить от имени администратора
• Здесь введите sfc / scannow и нажмите Входить
• Дождитесь завершения сканирования и начать сначала ваша машина
• Если SFC вернула ошибка заявив, что не удалось восстановить поврежденные файлы, выполните следующие команды, нажав Входить каждый раз:
  DISM / Онлайн / Очистка-Образ / CheckHealth
  DISM / Онлайн / Очистка-Изображение / ScanHealth
  DISM / Онлайн / Очистка-Образ / RestoreHealth

Способ 3. Попробуйте чистую загрузку

• Тип msconfig в поиске Windows нажмите Входить
• Перейти к Услуги вкладка
• Проверить Скрыть все службы Microsoft флажок и выберите Отключить все
• Перейти к Запускать вкладка и выберите Открыть диспетчер задач
• Здесь щелкните правой кнопкой мыши каждую запись и выберите Запрещать и закройте диспетчер задач
• Перейти к Ботинок вкладка, отметьте Безопасная загрузка и выберите Применить + ОК.

После загрузки обратно в Windows попробуйте запустить приложение, с которым у вас возникли проблемы. Если это решит вашу проблему, значит, виновато стороннее приложение. Чтобы исправить ошибку «Не удалось запустить приложение, потому что не удалось инициализировать подключаемый модуль платформы Qt», вам следует удалить все недавно установленные приложения и посмотреть, решит ли это вашу проблему в обычном режиме.

Способ 4. Переустановите указанное приложение

Вам следует попробовать удалить приложение, с которым у вас возникли проблемы, а затем установить его заново. Если вы имеете дело с OneDrive, вам следует сделать следующее:

• Нажмите Win + R на твоей клавиатуре
• в Бегать диалоговое окно, скопируйте и вставьте следующее:
  % userprofile% AppData Local Microsoft OneDrive Update OneDriveSetup.exe
• Пройдите этапы установки и начать сначала ваш компьютер
• Если Windows не может найти указанный файл, вам следует загрузить установочный файл с официального сайта [Прямая ссылка].

Если этот метод не работает и вы получаете сообщение об ошибке, перейдите к приведенному ниже методу, а затем повторите этот шаг.

Метод 5. Удалите проблемное приложение через командную строку

Удаление программы, которая не хочет удаляться, может быть трудным, хотя это возможно через PowerShell, так как вы можете запустить ее от имени администратора. Имейте в виду, что приведенный ниже пример относится к приложению OneDrive, и команда будет отличаться в зависимости от имени приложения и его местоположения.

• Открытым Командная строка от имени администратора как объяснено выше
• Скопируйте и вставьте следующие команды, нажав Входить после каждого:
  taskkill / f / im OneDrive.exe
  % SystemRoot% SysWOW64 OneDriveSetup.exe / удалить
• Примечание: если вы используете 32-битная система Windows вместо этого используйте следующую команду для удаления OneDrive:
  % SystemRoot% System32 OneDriveSetup.exe / удалить
• Это должно принудительно удалить приложение.
