    I recently reinstalled the windows due to vbinject virus and was surprised that my qt kit does no longer work with qt creator except for qt console projects

    these are the photos of my configs and problem

      Hi @user543120, how did you install your kit?

      Also, I'm curious... why is it labelled "Qt 4.8.7 (qt5)"? Is it Qt 4 or Qt 5?

        it's qt 4.8 but the folder name is qt5 , I know it's a bad idea

          @user543120

          Where did you get the Qt 4 from? Which compiler was used to build it?

          As you can see from the tooltip, MSVC 14.0 is not compatible.

          And yes, I would not call it Qt5. At least not, if you want help from others...

          Qt has to stay free or it will die.

            @aha_1980 I got it from the source nearly a year ago and was working with it until yesterday when I installed a new windows
            the warning always appeared but it doesn't cause any problems , also I'm now able to compile qt console applications very well

              Again: Which compiler was used to build the Qt4?

              Have you installed the service packs for MSVC 14.0?

                    during configuring qt 4.8 I got this in the configuration :
                    QMAKESPEC...................win32-msvc2015 (commandline)

                    is this the cause of the problem ?

                      the problem seems to be not appearing on qt creator 4.4 but when I installed new windows and downloaded qt creator 4.7 the qt 4.8 kit didn't work

                      did you drop the qt 4 support ?

                        Hi,

                        AFAIK, there was no support drop of Qt 4 in Qt Creator.

                        You can also install Qt 4.8.7 using the online installer. You can then check if there are other troubles with your version of Qt Creator.

                          I don't know if the Qt Creator engineers decided to drop support or not, but Qt 4 reached End-of-Life in December 2015. That means nobody checks if Qt 4 still works properly in newer products; it's possible that something broke but nobody realized.

                          You can try installing Qt Creator 4.4 and see if that helps: http://download.qt.io/official_releases/qtcreator/4.4/

                              If you need to support an old version of Qt, then I recommend you keep using Qt Creator 4.4.

                                It may be that nobody checks if Creator is still compatible with Qt4, but I can successfully work with Creator 4.7, Qt 4.8.2 and MSVC 2010 SP1, including debugging.

                                The Qt version was not self compiled, it was an official release.
