    @Ahti There is no such plug-in "welcome", the correct name is "Welcome". So, what exactly happens if you start QtCreator with -noload Welcome? Does it start and crash as before?

        Drop directory QtProject

              hi
              In win 7 , simply open start menu and paste
              %appdata% into the searchfield. it will open explorer at that location
              the delete or move the folder QtProject
              ( as to explain how i read @joaopagotto )

                Hello friend, can sometimes occur for a recording disk failure or something unexplained , Qt configuration files can corrupt .

                Open your Windows Explorer and type in the directory tab % AppData % which will take you to the directory that is the configuration files and startup QtCreator , this path has QtProject is where these files .

                Deleting this directory will cause the QtCreator recreate these configuration files and startup. Making the QtCreator boot normally.

                I my computer this %appdata% is C:\Users\user\AppData\Roaming

                  Hi, seems some problem with your video driver, try updating it again.
                  Also you can try this flavor of starting Qt Creator:
                  qtcreator.exe -noload Welcome -noload QmlProfilerExtension -noload QmlProfiler -noload QmlDesigner

                          Hi, to make Qt Creator start without those 4 plugins, start it one more time from CMD window, then goto Help, About Plugins, locate the 4 problematic ones and deselect their Load tick box. Now you should be able to start Qt Creator from the menu.

                          Developing Qt Quick apps will be more difficult without those plugins, so to fix it, perhaps check your OpenGL video driver. You could try installing Steam and test some game that requires OpenGL.

                              Since the Welcome plugin is disabled there's no welcome tab, so you'll have to open your projects via the File menu.

                                  You mean the "Recent projects"? That list on the Welcome tab is also visible in File Menu, Recent Projects.

                                  But best would be if you could get OpenGL up and running, then you could reenable those 4 plugins and get back the Welcome tab.
