I got this error when i start to run the windows application, To rectify this Error , I Opened The "Windows Task Manager" By "Ctrl+Alt+Delete" And Opened The Tab "Processes" And Selected The .exe Of The Application And Click On "End Process" Button And Run The Application Again...It Runs Successfully.
