      Thanks for your response.
      I downloaded the Qt5.1 from: http://download.qt-project.org/official_releases/qt/5.1/5.1.0/qt-windows-opensource-5.1.0-mingw48_opengl-x86-offline.exe
      After I installed, I have a folder: C:\Qt\Qt5.1.0
      I used all library from: C:\Qt\Qt5.1.0\5.1.0\mingw48_32\bin
      I searched and found a lot solution but no ones work for me.
      Note: I use Qwt-6.1.0 in my application, I build and install it by Command Prompt from Qt the I installed

        The MinGW in that package uses Dwarf-2 instead of SJLJ, so replace libgcc_s_sjlj-1.dll with libgcc_s_dw2-1.dll.

        Also, MinGW has changed: you don't need mingwm10.dll anymore, but you now need libwinpthread-1.dll

          @JKSH: Thanks for your advice.
          I did copy all the files you mention to application folder, I all so put platform folder as well.
          But somehow the application still show Visual C++ Runtime error when I run it in other PC.
          Very confused now.
          Please advice.
          Thanks

            If it's showing a Visual C++ error, that means your binary was compiled with Visual Studio, not MinGW... Check that:

            You are using the correct Qt package

            You are using the correct compiler

              I used MingW, to make sure nothing wrong, I removed the msvc-2010 from the Qt installed directory, but the error still happened.
              It pop up a window with message: "This application has requested the Rumtime to terminate it in an unsual qat. Please contact...."

                "This application has requested the Runtime to terminate it in an unusual way" is definitely a Visual Studio message. You need to clean your environment.

                Uninstall all versions of Qt except for the MinGW one. Remove Visual Studio from your PATH. Delete your *.o and *.exe files and recompile.

                If you still can't solve the problem, uninstall Visual Studio and try again.

                  Hi JKSH,
                  I did all things you mention, but when I run my app on another PC, it pop up another message: "The application failed to start because it could not find or load platform plugin "windows". Reinstalling the application may fix this problem"
                  When I click OK, it come with Visual C++ Runtime library error.
                  Don't know why this happen, even I copy the platforms/qwindows.dll from mingw_32/bin.
                  Any idea to fix this?

                    Can you run the application from your development PC, in Qt Creator?

                    Can you run the application from your development PC, outside of Qt Creator (double-click the .exe)?

                    Did you install Qt on your other PC? You must not have Qt in your PATH. If you do, your application might try to use the wrong version of DLLs.

                    qwindows.dll must be in a subfolder:
                    myapp\myapp.exe
                    myapp\Qt5Core.dll
                    myapp\platforms\qwindows.dll

                          Hmm... Please open your project in Qt Creator and provide screenshots of the following:

                          • (Top menu bar) -> Tools -> Options -> Build & Run -> Compilers
                          • (Top menu bar) ->Tools -> Options -> Build & Run -> Kits
                          • (Left menu bar) -> Projects

                          Is this the same project that you are trying to run on your other PC? Can you provide a GitHub link?

                            I did an experiment by uninstall all Qt from my PC then run the app
                            myapp/app.exe
                            myapp/*dll (all dlls required to run the app)
                            myapp/platforms/qwindows.dll

                            The error message appeared.

                            Then I Re-Install Qt5.1 MingW32
                            The App run OK, withou error message.
                            Do you have any idea?
                            I did check the Path in Environment Variables, don't have any value related to Qt installed folder.

                              Hi JKSH,
                              I used Process Monitor program then I found something interesting:

                              • The Application has error always used files from Qt Install Directory, e.g: platforms.
                              • I create a similart app, It uses files from directory that I copy.
                                Here is the situaton, all file in a folder in D drive, Qt Install in C:\Qt:
                                D:\MyProject
                                MyApp.exe
                                *.dll (All required dll: Qt5Core.dll, Qt5Gui.dll,...
                                platforms/qwindows.dll
                                MySimilarApp.exe
                                If I rename Qt5.1 to Qt5.1___ (for example)
                                MyApp.exe ran with error.
                                But when I return the name to origial one: Qt5.1, MyApp.exe ran withou error.
                                MySimilarApp.exe ran without error, don't care the Qt5.1 folder name.

                              I don't know why this happened.

                                Very strange... I've never seen that before.

                                You said MySimilarApp.exe is ok. What happens if you re-compile Qwt and MyApp.exe after you uninstalled and reinstalled Qt 5.1?

                                  [SOLVED]
                                  I solved the problem.
                                  The error caused by some QImage Variables I declared at the top of mainwindow.cpp (after #include, of course).
                                  By moving these variables to mainwindow.hpp, it works perfectly.
                                  Special thanks to:
                                  JKSH for your willingness to support me.
                                  Process Monitor enabled me to captured and isolated the root cause.
