NOTE: The recommended way to deploy your application is to use the official deployment tool (windeployqt). Try that first! Continue reading this guide only if windeployqt doesn’t quite work for you.

This tutorial shows where you download and install Qt Creator on Windows 10 Buy Me A Coffeehttps://www.buymeacoffee.com/guitutorials. QT platform plugin ‘windows’ Hello, I download an app of R (programming language) and at the time of opening this poster appears: ‘This aplication failed to start because it could not find or load the Qt platform plugin ‘Windows’ reinstalling the application may fix the problem’. ‘This application failed to start because it could not find or load the Qt platform plugin ‘windows’. Reinstall the application may fix this problem.’ Error, due to the AdSSO, appears when launch Autodesk Software.

The windeployqt tool will gather files from a few different locations. Here is an example of an app that uses Qt Quick to display a picture (PACKAGE-SPECIFIC DLLS ARE NOT SHOWN):

Sometimes, your app might be missing some functionality after deployment. Perhaps a window is blank, an image doesn’t show, or a music file won’t play. If this happens, windeployqt has probably forgotten to include a file that is only loaded at runtime (like a plug-in DLL).

Here is a systematic (albeit brute-force) way to identify the missing files. This guide is written for Qt 5 and assumes that:

• The release version of your app works correctly when you build + run it from Qt Creator
• Your (dynamically-linked) copy of Qt is installed in C:Qt5.2.1mingw48_32

Initial deployment (Quick and dirty)

1. Close Qt Creator.
2. Copy the following into C:Deployment
   1. The release version of MyApp.exe
   2. All the .dll files from C:Qt5.2.1mingw48_32bin
   3. All the folders from C:Qt5.2.1mingw48_32plugins
   4. (If you used QML) All the folders from C:Qt5.2.1mingw48_32qml
3. Rename C:Qt to C:QtHidden (This turns your PC into a clean environment, just like one that doesn’t have Qt installed).
4. Launch C:DeploymentMyApp.exe.

If your app worked correctly, congratulations! You are almost ready for deployment. You don’t want to ship a 1.5GB package though, so it’s time to clean up unused files.

If it didn’t work correctly, ask for help (see the Appendix)

Final deployment (Cleaned up)

Do the deletion steps below in C:Deployment and all of its subdirectories. After each deletion, launch C:DeploymentMyApp.exe and test it. If it stops working, restore the files you just deleted.

1. Launch MyApp.exe. While it is running, try to delete all DLLs. The DLLs that aren’t used will go to the recycle bin, leaving behind only the DLLs that you need. (This trick doesn’t work for .qml and qmldir files, however).
2. (If you used QML) Delete a few .qml files and try relaunching MyApp.exe. Repeat until you try all .qml files.
3. (If you used QML) Delete qmldir files from the folders that have no more DLLs or .qml files

When you have removed all the files that you don’t need,

1. Rename C:QtHidden back to C:Qt to restore your installation.
2. Distribute your app.

If you still get stuck,

1. Start a new post in the Qt Project forum
2. Say that you followed this guide. Say which attempts passed, and which attempts failed.
3. Describe how it fails, and provide any error messages that you see.
4. Provide a screenshot of the contents in C:Deployment

Remember: The more info you provide, the better your chances of getting a solution!

Qt is a cross-platform software that was designed to create graphical user interfaces and cross-platform applications on Windows, Linux, macOS, and Android. However, when something went wrong with the Qt platform, you may receive the “This application failed to start because it could not find or load the Qt platform plugin Windows” error.

It seems like reinstalling the application may fix the error. However, some users encounter new errors when reinstalling the app. Don’t worry. Here we explore several effective troubleshooting methods. Let’s try.

How to Fix the “No Qt Platform Plugin Could Be Initialized” Error

After analyzing extensive user reports, we summarize the 6 applicable ways to fix the Qt platform plugin Windows error. You can try them in order until the error gets solved or choose the ones that work best for you.

Fix 1. Replace the Qt Files in the Destination

The first and proven method is to replace the Qt files in the destination folder. Here we take Python for example. To do so, follow the steps below:

Step 1. Press the Win + E keys to open the File Explorer, select This PC, type pyqt5_tools in the search box, and hit Enter.

Step 2. Right-click the pyqt5_tools folder once the search is complete and select Open folder location.

Step 3. Then go to the folder path “PyQt5 > Qt > plugins”, and then open the Plugin folder, right-click the platforms folder, and select Copy.

Step 4. Go to the site-packages folder that you initially opened and go to pyqt5_tools > Qt > bin.

Step 5. Right-click any empty space inside the bin directory and select paste. Then confirm it when you see the “Replace the files in the destination” message.

Now, you can relaunch the app and see if the “this application failed to start Qt platform Windows” message persists.

Fix 2. Perform a Clean Boot

One of the possible reasons for the “this application failed to start Qt platform Windows” error is third-party software conflicts. If you are not sure which app is causing the conflict, you can perform a clean boot (click on the Hyperlink to know the detailed steps). Once you find out the conflicting software, uninstall it and check if the error is fixed.

Fix 3. Check System File Corruption

Sometimes corrupted system files can trigger various errors and issues when running your apps such as the “no Qt platform plugin could be initialized” error. So, we recommend you run an SFC scan or DISM to check system files.

Step 1. Type cmd in the search box, and then right-click Command Prompt and select Run as administrator option.

Step 2. Type the sfc /scannow command in the elevated command prompt and hit Enter. After that, the SFC tool will scan and try to repair the corrupted system files automatically.

Step 3. If the SFC command was unable to repair corrupt system files, you can try running the following DISM commands:

• DISM /Online /Cleanup-Image /CheckHealth
• DISM /Online /Cleanup-Image /ScanHealth
• DISM /Online /Cleanup-Image /RestoreHealth

Fix 4. Reinstall the App

As the error message hints, reinstalling the application may help fix the problem. However, many users cannot uninstall the app smoothly. Don’t worry. We summarize the following 3 applicable ways to reinstall the app. (Here we take reinstalling OneDrive for example)

Uninstall OneDrive via the Run box:

Step 1, Press Win + R keys to open the Run dialog box, and then type the following command in it and hit Enter. Here make sure you replace the OneDriveSetup.exe path with the actual location.

Uninstall OneDrive from Settings:

Step 1. Right-click the Start menu at the bottom left and select Apps and Features.
