    hello, I installed Visual studio 2022, then I installed QT (msvc + mingw), but as I said, I can't run it, it gives all kinds of errors. I brought C++ Build 17 but nothing changed. What exactly should I do while installing?
    It cannot logically find the exe to run because the compilation is not working properly. I tried it in VS 2019 and it was the same on it.

    Build started...

      @HerrWinfried Have you installed Windows SDK?

      For more information please re-read.

      Kind Regards,

          @HerrWinfried This is the C++ standard you use. This does not answer @artwaw's question if you properly installed the WindowsSDK. The error you're showing us does not come from Qt but from a missing header file provided by MSVC / WindowsSDK - there is nothing Qt can do against this.

            Qt6 requires c++17. Try the following:
            To set this for a project:

            1. Right click a project, go to Properties
            2. Select Configuration Properties > C/C++ > Language
            3. For C++ Language Standard select "ISO C++17 Standard (/std:c++17)"

              Thanks for the info, I'll upload it again and have a look.
              The strange thing is that I can compile via QT Creator. however, an exclamation point appears next to it on the build screen.

              I mentioned it in the image above, it's already set like that. Thanks anyway.

                @HerrWinfried It might have been added to your project.
                Check your pro file and you may find
                CONFIG += c++17

                if you use cmake, it may have included
                set(CMAKE_CXX_STANDARD 17)

                But I am surprised that vs 2022 does not have c++17 as default

                    Perhaps, but you select an x86 debugger for a amd64 compiler. I don't thing this is valid configuration.

                        @HerrWinfried I guess Qt does not yet support C++ compiler from Visual Studio 2022.
                        You can ask Qt devs on their mailing list.

                          Visual Studio 2022 toolchain support/detection has been added into Qt Creator 6.0 (cf release note: https://code.qt.io/cgit/qt-creator/qt-creator.git/plain/dist/changes-6.0.0.md)
                          First RC has been published at 11.11 (cf. https://www.qt.io/blog/qt-creator-6-rc-released)

                            I guess Qt does not yet support C++ compiler from Visual Studio 2022.
                            You can ask Qt devs on their mailing list.

                            Sounds like something that won't fix my problem in visual studio 2022. Thanks again for the information.

                              @HerrWinfried According to https://www.qt.io/blog/qt-vs-tools-for-visual-studio-2022 it should work, but I'm not sure about Qt itself.

                                That's the point that confuses me, but anyway, I prefer to wait a few weeks for now.

                                  The problem is that VS2022 doesn't return by default the right value for

                                  __cplusplus
                                  

                                  No idea if that's a bug or a feature in VS2022. However, here the solution how to overcome this issue:
