    Hello,
    Thats my first application with QT5 in win10, 64 bit. A simple mainwindow.
    Outside of creator it won't start. I ran windeployqt and added "libgcc_s_dw2-1.dll".
    error: " procedure entry point not found ......... in Qt5core.dll".
    It copied the app to "C:\Qt\5.15.2\mingw81_32\bin", here it worked.
    What is going wrong?

      Hi and welcome to devnet,

      Check the dependencies with a tool like Dependency Walker to see what might be missing.

            I dont't know how to interpret the results. On the first level of dependency walker I see 7 dll's.
            QT5CORE.DLL, QT5WIDGETS.DLL, LIBGCC_S_DW2-1.DLL, LIBSTDC++-6.DLL, KERNEL32.DLL, MSVCRT.DLL, SHELL32.DLL. The last three are not in my release directory. If i go some levels deeper, there are much warnings.

              the module warnings are on "kernel32.dll", "msvcrt.dll", and "shell32.dll"
