    well depends on what you want to build.
    If YES to normal Desktop type of program ( like a desktop game) then you should only install
    the Mingw shown in image. That way, it should just work. without further setup.

        In that case, it would be good to start here and read it carefully.
        https://doc.qt.io/qt-5/android-getting-started.html
        As there are more things you must install on your own.

        you will also need one of the arm Qt prebuilds also.

            and you did install the mingw this time ?

            It seems the project is un configured so either no kits was shown to you or
            you didnt select one.

            what did it show in Kit selection when you made the project ?

                and you select that kit and press next ?
                It should not say unconfigured at the "screen" button then.

                      Hi
                      well something did went wrong.
                      Could you please first remove all of Qt.
                      Then reboot
                      and then install the mingw Qt packet.
                      We could also try fiddling with the kits but
                      often a reinstall is faster if you have ok internet.

                        Hey @MongKong,

                        I had recently problems when installing Qt. So I wrote a mini-list of what to do after completely uninstalling Qt, if it can help you:

                        1. When installing Qt, select:
                          a. the latest version of Qt
                          b. the latest compiler version. Choose the MinGW compiler and select the MinGW kit, but not all the MSCV kits.
                          c. the latest framework version
                          d. a debugger is selected by default

                        2. When creating a new project, if necessary, unblock the firewalls of your antivirus.

                        3. When creating a new project, if necessary, go to tools->options and select the kit corresponding to the compiler (show the pathway).

                          0_1551039452192_2949e997-c12f-45fa-b7ac-ff88818e5a83-image.png

                          Tried creating a project again...still same thing....
                          @EvanZ
                          about the tools->options thingy, what do i do, do i press on Desktop Qt 5.12.1 MinGW and press add ? :
                          0_1551039568098_ab97a228-8ad6-4e9d-97ac-2f3db47f0618-image.png

                          And another thing, when i try opening projects i get this:
                          0_1551039635957_4a2bbea4-034c-4679-a142-81c3ae6615fe-image.png

                            Hi,

                            If you over over the yellow warning sign, you'll have more information about what is wrong.

                            You should also check the Compilers panel.

                              Hi
                              That is really odd. normally mingw just works,
                              Do you have any other version of mingw installed ?
                              Do you have Avast virus scanner installed ?

                                  Looks like you are trying to use a 32bit build of MinGW for a 64bit build of Qt.

                                    Yep, thank you for realizing that !!!
                                    it was set for this : F:\Qt\Tools\mingw730_32\bin\g++.exe
                                    so i changed it to this: F:\Qt\Tools\mingw730_64\bin\g++.exe
                                    now it's working fine :D
