        Hi, just a guess, but if you have an antivirus program running, try disabling that.

            When you try starting Qt, do you get an error message?

                Hmm what version of Qt is that?
                Also, to make sure, this is not Apple QuickTime that won't start?

                      Maybe if you try to start it from a CMD window there will be an error message, try:

                      cd /d C:\Qt\Qt5.5.1\Tools\QtCreator\bin
                      qtcreator.exe
                      

                      (Note: I'm guessing the file path to your Qt Creator, it could be slightly different.)

                        This usually happens when your graphics card does not support high enough OpenGL version. Try running Qt Creator with OpenGL plugins disabled like this:

                        <path to your installation dir>\qtcreator.exe -noload Welcome -noload QmlDesigner -noload QmlProfiler
                        

                        Btw. QT stands for "Apple Quick Time", Qt is a name of a library and you're having problems running Qt Creator, not Qt.

                          @Chris-Kawa Thank you very much, it worked for me!
                          The Qt Creator is working yesterday, but today is not alright. It issues Qt Creator has stopped working.
                          So I think my graphics card can support OpenGL version, but it's driver is not good enough.
                          By the way, I have an antivirus program running and scan computer yesterday.
                          Is my understanding right, please?
                          Could you help me, please?
                          Best Regards!

                            I have fixed the problem: uninstall the graphics card driver and then re-install it.
