    Hello all,

    I recently installed Qt 5.11.2 (IDE: Qt Creator 4.7.1) and went for running one of earlier programs called Hello. But the problem is I have two kits Android Arm 7 and Android X86 but the Desktop kit is grayed out. I tried, using my previous information work it out but yet it's disabled.
    How to solve this problem please?

    Hi @tomy,

    can you please show a screenshot where this is grayed out?

    Regards

    Qt has to stay free or it will die.

        @tomy Please show your Desktop kit, there is probably a problem with it.

            yes this page,

            most glaring error from this screen shot is the missing Qt version: none can you select the desktop qt version there ? if not not did you install the Qt libaries for your desktop system ?

              @J.Hilk

              I clicked it and there were only the prior Android kits in the drop-down menu of it.

              did you install the Qt libaries for your desktop system

              I down't know what they are! :(
              I just uninstalled my begone Qt and installed this new one on my Windows 7 X64 machine. Of course, afterwards I installed Android Studio and downloaded a huge size of SDK.
              Now what should I do please?

                  I probably think that the answer of @jsulm can solve it.

                  In additional information, I think that you have installed only Qt version of Android.
                  Please additionally install MinGW 5.3.0 32 bit for Desktop.

                  <Update method>

                  • Qt Maintenance Tool(online update) select "Add or remove components"
                  • Please select as below.
                    Qt 5.11.2
                    `-
                    MinGW 5.3.0 32 bit

                  0_1544434852150_MaintenanceTool.png

                  If this solutions does't succeed, you give our about a screenshot at Qt Versions tag of Kits, We probably can give a more appropriate solution.

                    Thank you both very much.
                    When I go for Maintenance Tool, simply skip the Qt Account window, then Add/Remove component -> Next. Then it says: At least one valid and enabled repository required for this action to succeed.
                    What to do with that? I'm not used to it.
                    How to be rid of that, please?

                        I don't use an online SDK I think. :(
                        I also clicked on the link given in Alternative Instructions but it says "page not found".
                        The process seems very complicated. I don't know why such an obstacle should be on the way of using Maintenance Tool!
                        Previously I was used to creating a temporary folder name and it'd go fine. Now it doesn't work seemingly!
                        By the way, I'm sure when installing Qt I checked the tick for MinGw because I knew this. Still can't figure out all the above problems! :(

                          "The process seems very complicated" - usually there is nothing complicated if you used online installer. Some repositories can cause problems (offline/bad connection) .

                            you can check your installation folder

                            besides your android installation should be a folder for mingw, if it isn't than you did not install it. If there is such a folder then QTC did not pick it up automatically and you may have to manual manage your kits

                              There are only Android versions.

                              Yes, I used the offline file. A bad choice probably! :(
                              Should uninstall this one a use the online installer this time?

                                No folder except for Android ones. I'm almost completely sure I checked the tick for MinGW. I even took a screen shot before installing - I don't know why but likely for this situation!

                                  @tomy From this screen shot I don't see whether you checked Qt for MinGW.
                                  I would uninstall and use online installer, so next time you can use Qt Maintenance Tool to update or add/remove Qt versions.

                                    @tomy From this screen shot I don't see whether you checked Qt for MinGW.
                                    I would uninstall and use online installer, so next time you can use Qt Maintenance Tool to update or add/remove Qt versions.

                                    OK I go for uninstalling and reinstalling using the online method.
                                    But, doesn't the check for MinGW 5.3.0 in the very bottom, mean the Desktop kit you meant?

                                      Hi
                                      The one in bottom is the actual compiler.

                                      The one KazuoAsano shows in his shot is
                                      a precompiled Qt version/binary for that compiler.

                                      Just select the mingw Qt version higher up and it will select the right compiler to
                                      install also.

                                        Hi and thank you.
                                        I uninstalled the prior version and selected the following items on the wizard for the new Qt using the online installer.
                                        Please if possible check whether or not correct boxes have been checked. :)

                                          Hi did you manually select the mingGW 5.3 ( below)?
                                          I wonder as the Qt bin mingw you checked higher up
                                          is for mingw 7.3

                                          also, you do have visual studio installed already, correct ?
