    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.

                  @ru10 Qt6 uses CMake instead of QMake (thoufh you still can use QMake), so look for CMakeLists.txt file.
                  "And also getting ui_mainwindow.h not found" - this file is generated when you build your project, you should not edit it as your changes will disappear next time this file is generated.

                      "And also getting ui_mainwindow.h not found" - this file is generated when you build your project

                      Have you tried building your project? You will get these messages until you do.....
