qt examples doesnt start after deployment with windeployqt.exe
-
Hi everybody, i am new to Qt development., Just recently installed the latest version of Qt 5.14.2 + VS2019 Pro (Windows 10) . I can run the examples inside the Qt Creator without any problem, but cant deploy the examples using windeployqt.exe... I did everything like in this video instruction: https://www.youtube.com/watch?v=gnpPosTbttM&list=PLQMs5svASiXNx0UX7tVTncos4j0j9rRa4&index=3
but after deployment procedure .exe just doesnt start (no errors and no GUI is shown up) . I tried diiferent examples (dashboard, quickGamepad, automotive and so on.. behavior is the same cant start exe outside of Qt Creator)
Help me please to find a solution...

You are using Qt Quick, you need to use the --qmldir and point it to the folder containing your application qml files.

Hi and welcome to devnet,
What exact example are you testing ?
Qt 32 or 64 bit ? -
Try to run the .exe from command line (cmd.exe) and see if you get any warnings or errors printed.

- Qt 64 bit
- Also tried 32 bit, the same problem just no errors no windows outside the Qt Creator

How did you call windeployqt exactly ?

- Copied automotive.exe (release) to new folder called "Deploy"
- Run the Qt command prompt "Qt 5.14.2 (MSVC 2017 64-bit)"
- Here is my console output:
