    Yes it's correct
    There are no spaces in the file

    QT. += core GUI
    

    should be

    QT += core gui
    

    And as @artwaw said: rerun qmake and rebuild.

      Apart from previous posts, looks like you changed the UI file name.
      FORMS += main window.ui

      I'm seeing blank space between main and window.ui. Is it mainwindow.ui or window.ui ? If it is window.ui,it must be generating ui_window.h file. Please check that. So you must include the ui_windows.h instead of ui_mainwindow.h

        QT += core gui

        greaterThan(QT_MAJOR_VERSION, 4) : QT += widgets

        TARGET = test
        TEMPLATE = app

        SOURCES += main.cpp
        mainwindow.cpp

        HEADERS += mainwindow.h

        FORMS += mainwindow.ui

            This looks ok. Do you have the problem still ? Can you create a new project with all default settings in your QtCreator & check everything works ?

              Yes I created a new project but the problem is still coming. Also there was Qt5cored.dll file which was missing. I added that also.
              Is this problem because of that?

                Ok. I suspect that issue with your installation. One last check b4 u get into further. I'm assuiming that you are working on windows system. Do you see uic.exe executable in bin directory of your installation ?

                      @jsulm
                      Downloaded the software and installed it.
                      It was working correctly when I installed it. After some time it started giving me this error.
                      As far as I know, there is some issue with my Qt5core.dll file

                        @Tanuja What is the issue with Qt5core.dll?
                        You could try to install the latest Qt version (5.9.1).

                            as @jsulm already suggested, you better install the new version and try. My suspect is that you have installed some other software which has old Qt library in path. This must be causing the issue.

                                  Hi ,
                                  Just yesterday I installed QT 6.3.2. When I started new project in Qt creator, .pro or make file is not generated ...And also getting ui_mainwindow.h not found.

                                  Please suggest on how to create .pro file.
                                  Thank you.

                                    @ru10 Qt6 uses CMake instead of QMake (thoufh you still can use QMake), so look for CMakeLists.txt file.
