      I update my Qt version from 5.70 to the latest, .5.12.1, With the old version, everything works fine: after update, I try to launch my app, and this is the result:

      There is something new that I need to know?

      Thank you in advance

        @UnitScan Did you try a complete rebuild (delete build folder, run qmake and build)?

                  mmh, can you show us the kit's & compiler tab of your configuration/settings of QtCreator.

                  Seems as if there's something not ok.

                      well yes,
                      you have mingw compiler assigned to MSVC precompiled Qt-Libs. Unsurprisingly this does not work.

                      You need msvc compiler for that precompiled QT-Lib or you need to download the mingw-libs.

                          how did you install Qt to begin with ?

                          If you used the online installer, you can use that tool to add missing features:

                          0_1549289555417_558e21fe-73cf-4371-a4a9-63d455e69b6d-image.png

                          If you used the offline installer than you'll have to deinstall Qt completely first, as the offlineinstaller does not allow for later changes.

                              Yes, that is currently an issue, there are talks of adding mingw32 precompiled libs to the downloader, but that's still up for discussion.

                              You have 3 Options than,

                              • switching back to 5.11.3, IIRC those have precompiled 32 bit libs for mingw
                              • installing MSVC compiler(for legal reasons you have to get them manually from Microsoft)
                              • compiling 5.12.1 yourself

                                  Hi @UnitScan,

                                  so please mark this topic as SOLVED too. Thanks!

                                  Qt has to stay free or it will die.
