    QtCreator should be in C:\Qt\5.6.0\Tools
    You can create a Kit with the right compiler and Qt version in QtCreator under Tools/Options/Build & Run

        If it is there you should find it.
        But here is the path: C:\Qt\5.6.0\Tools\QtCreator\bin\qtcreator.exe

          Thanks, It works now, but how can I replace it on desktop with previous Qt5.5 creator?

            You mean you want to have a short-cut on the desktop? Drag and drop qtcreator.exe to the desktop using right mouse button and then select "Create shortcuts here"

                First thing: don't use cout since it will send the text to the console.

                You can simply put a QLabel with hello world as text as central widget of your MainWindow class.

                  Previously I tried a simple project to print out "Hello world" in one of my previous posts. The C++ code was written in MSVC 2013 gives output. Here is one of my previous posts related to getting output of C++ code written in MCVS 2013 in Qt5.5.
                  Here is my previous post:
                  "The above output was the debug using "Desktop Qt 5.5.1 MSVC2013 64 bit". I didnt debug with MinGW. The problem is the way I use to get the results in UI.
                  I tried a simple project to print out "Hello world", the C++ code written in MSVC gives output. Could you please take a look at my files:
                  Here are the content of C++ all files.
                  main.cpp
                  Bucky9.cpp
                  stdafx.cpp
                  targetver.h
                  stdafx.h
                  Now I created a Qt widget project, and I added the C++ code stdafx.h, targetver.h, and stdfx.cpp files using "Add existing Files" to the header and source. I didnt add Bucky9.cpp and main.cpp. Instead, I coppied the main.cpp C++ codes in the Qt main.cpp file with a little changes of all files.
                  (Changes: 1- Bucky9 is not included in Qt.
                  2- In stdafx.h #include <char.h> instead of <tchar.h>
                  3- Including #include "stdafx.h" in mainwindow.cpp.

                  Here are the content of all files in Qt project:
                  main.cpp
                  mainwindow.cpp
                  stdafx.cpp
                  stdafx.h
                  targetver.h
                  mainwindow.h"

                  I could get "Hello worlds" with QLabel using Qt5.5 and MCVS 2013. The only difference is that I didnt change <tchar.h> in stdafx.h. Now, when I run it, it builds it, but the run button is not active. Here is the code: Qt code
                  Is there any change when I am working with MCVS 2015 and Qt 5.6 beta? Some of my Qt 5.5. works, but some of them dont work.

                      Thanks it worked today, the run button was active and gave "Hello world" in widget.
                      Just I am doing the same with another longer C++ code. I copied all .h and .cpp files to the created Qt project folder and added using
                      "Add existing file" to Qt .h and .cpp files. But instead of main.cpp in Qt, I copied the .cpp code in my PS C++ project. When I run it it gives more than 10 errors like

                      
                      "\\home.org.a\ab\data\Documents\Qt projects\PS7\main.cpp:1060: error: C2664: 'void PSError(char *)': cannot convert argument 1 from 'const char [37]' to 'char *'' in main.cpp file.
                      
                      

                      I changed the the #include <tchar.h> to #include <char.h> in "stdafx.h" file, but the error decreased to two including ```

                      "\\home.org.a\ab\data\Documents\Qt projects\PS7\stdafx.h:11: error: C1083: Cannot open include file: 'char.h': No such file or directory"
                      
                      
                      PS. May I ask why I cannot see my previous posts in this page? I need sometimes to look at them, how can I do that?

                        Just to be clear, are you trying to build MSVC generate code with a MinGW build of Qt ?
                        If so why not just import the code you wrote in your VS project in your Qt project and dump the VS specific files that you anyway will not use in your Qt project ?

                        If you have the infinite scroll activated, just scroll up otherwise you have a at the bottom a page selector.

                          I think I wrote by mistake. I am trying to run my C++ project using Qt Widget project.
                          I have these files VS I copied them in my Qt project folder, and added stdafx.cpp, stdafx.h, targetver.h and O_PS .H to the Qt. Instead of adding "O_PS .cpp" I copied its content to the "main.cpp" in Qt. For "po .cpp" also I just added
                          #include "stdafx.h" to the "mainwindow.cpp". Now I have these files in Qt: Qt

                          The errors were explained in the previous post.

                              If I understood your post, I dont run the Qt with MinGW, here I run it using Desktop MCVS 2015 compiler, after adding the path of the input data file to the Run of the MCVS 2015 in the project.

                                  Please take a look at error messages you get:

                                  "\\home.org.a\ab\data\Documents\Qt projects\PS7\main.cpp:1060: error: C2664: 'void PSError(char *)': cannot convert argument 1 from 'const char [37]' to 'char *'' in main.cpp file.
                                  

                                  Now check the code lines mentioned in these error messages. Error message you posted tells you that you are passing a const char array to a function that takes a non-const char*. This is not allowed.

                                    But previously it did not give that error, when I did the same with different versions of Qt5.5 and MCVS 2013. The number of errors

                                        But previously it did not give that error, when I did the same with different versions of Qt5.5 and MCVS 2013. The number of errors

                                         cannot convert argument 1 from 'const char [37]' to 'char *''
                                        

                                        is about 12-13.
                                        However, when I change the

                                        #include <tchar.h>
                                        

                                        to

                                        #inclu```de <char.h>
                                        

                                        in "stdafx.h" file, the error decreased to two including

                                        \\home.org.a\ab\data\Documents\Qt projects\PS7\stdafx.h:11: error: C1083: Cannot open include file: 'char.h': No such file or directory
                                        

                                        errors.
