    Hi Folks , I've been trying to deploy and test my qt .exe on another Windows machine.
    When attempting to launch the application , the GUI gets displayed for a split second until it goes blank. I know for a fact that it runs , since it does not exit right after it goes blank , and am able to see my drop down menus if I click on their respective positions in the blank window.

    Anyone know how I can go about resolving this issue ?

      @RudyRaph I assume qt.exe is your application.

      Did you run windeployqt on it, to gather all the plugins and dependencies? Looks like something from the set is missing.

      For more information please re-read.

      Kind Regards,
      Artur

        @artwaw Yes I am referring to qt.exe as my application , I did run windeployqt on it ,and added the missing .dll's of my dependencies as well to my release folder.

        I should mention that I was able to successfully run the application on a windows virtual machine , but due to graphical limitations was forced to test it out on a physical machine.

          ~ Your Graphics driver or OpenGL might be causing the issue
