Why is my QT application not working?



  • I built a Qt 5 application using Qt Creator on Windows 7 64 bit (using msvc 2010). The application runs perfectly on my computer but it won't work on other computers.

    I copied all the .dlls which were shown as missing in Dependency Walker into the program folder and there is no error, but the apps just won't run.

    I've tested it on Windows XP and Windows 7 64 and 32 bit.
    What can I do in order to find out what's wrong?

    UPDATE: i installed Qt 4.8.4 (vs 2008) and msvc 2008 express and i compiled it and it's runs on other computers, with the .dlls of Qt4. maybe someone know what the problem with Qt5...

    Thanks in Advance

    Hi and welcome to devnet,

    You are likely missing the plugins. You should use windeployqt to gather all the needed dependencies for your application.
