      That errors means you are trying to link to a MinGW32 library which is not a good idea since you are using Visual Studio.

      Do you have that library hardcoded in your project ?

        I actually dont run Qt libraries from Visual studio i would like to use Qt creator and connect compiler manualy. Is there some easy way to start Qt 64 bit on windows without Vs (can be some older version) THanks for help again

          Just install the MinGW package. It provides both Qt and the MinGW compiler (verify the options)

            I have followed this example but stil not working

            Before continuing to next steps make sure u have downloaded latest version of Qt.

            Download and install minGW-64-bit from link: https://sourceforge.net/projects/mingw-w64/files/latest/download
            Remember The directory to which you install minGW.
            Open Qt creator and go to tools -> options -> Build and Run
            In Compilers tab Select add -> MinGW ->
            Name: MinGW
            path: Browse for mingw-w64.bat (you will find this file in the directory in which you have installed MinGW).
            ABI: x86 Windows msvc2015 pe 64bit

            Don't forget to apply your edits.
            Go to Kit -> add
            Name: GCC
            Device Type: Desktop
            Device: Local PC (Default for desktop)
            Compiler: minGW
            Qt Version: select newest version

            Apply changes and restart qt
            While creating new project make sure you use GCC as kit

              There's no need to go grab an external version of MinGW. The Qt installer already provides it.

                  Because it's the offline installer for MSVC2015.

                  Either grab the offline installer for MinGW or better yet, use the Online installer. With that one you can choose which version of Qt you want to install and easily upgrade.

                      Because currently there's no official package of MinGW64 from the Qt Company.

                      Out of curiosity, do you really need to build in 64bit ?
