      @Biradar On which OS are you? Why do you use such an old Qt and QtCreator version?
      What do you mean by "open"? Are you building that widget application in QtCreator and try to start it from there? Or do you start the application from outside of QtCreator?

        Are you able to open the QtCreator ?
        Are you able to create the project ?
        Are you able to build the project ?
        Is build successful ?

            looks like you old Qt in the path. Just check what settings you have under Qt Creator. Open the QtCreator ->Tools->options->Build-Run-Kits.

            Can you check which kits are available ? Does it show any "ReD" mark for any of the kits ?

              /qt4project/main.cpp

              Is this really the whole path?!

                  What is in /usr/share/qtcreator/templetes ?
                  It looks like either QtCreator installation is broken or not complete (project templates are missing).

                      @Biradar How did you install QtCreator? Did you install RPM package which RHEL provides? If so then use rpm to remove/install. Also you should check whether RHEL splits QtCreator into several packages.

                          @Biradar This is a quite old QtCreator version.
                          You should use the Qt Online Installer to download and install Qt and QtCreator.
