        Thanks,[/quote]That means your program crashed. Does it run properly on your development PC?

        Did you remember to include platforms\qwindows.dll?

        What OS does your development PC use? What OS does your target PC use?

        All programs will look for DLLs in the same folder as the .exe -- that is normal. If you look inside C:\Program Files, you can see that most programs put the .dll files together with the .exe files.

        If you want to be tidy and clear, put a Shortcut on your desktop.

          1.It's run fine when I run it on my development PC.

          2.I forgot include platforms\qwindows.dll.

          3.I use win7-32bit at development PC and target PC use win7-32bit too.

          I have been checking how to add platforms\qwindows.dll to my project.

          Will I copy it to \release\platforms\qwindows.dll and run executable file.

          It didn't work in here. Will I reconfigure something at .pro file?

            [quote]3.I use win7-32bit at development PC and target PC use win7-32bit too.[/quote]Ok, that should be easier then. (Deployment is harder if you build on Windows 7 and transfer to Windows XP)

            Will I copy it to \release\platforms\qwindows.dll and run executable file. [/quote]Yes, that is correct. Your folder should look like this:

            \release\application.exe
            \release\Qt5Core.dll
            \release\Qt5Gui.dll
            \release\Qt5Sql.dll
            \release\Qt5Widgets.dll
            \release\icudt51.dll
            \release\icuin51.dll
            \release\icuuc51.dll
            \release\libgcc_s_dw2-1.dll
            \release\libstdc++-6.dll
            \release\libwinpthread-1.dll
            \release\platforms\qwindows.dll

            (but maybe it needs more. Did you use "Process Explorer":http://technet.microsoft.com/en-au/sysinternals/bb896653.aspx, as suggested by 1+1=2?)

            [quote]It didn't work in here. Will I reconfigure something at .pro file?
            [/quote]No, the .pro file is only for compiling and linking.

                    C:\Qt\Qt5.1.0\5.1.0\mingw48_32\plugins\imageformats\qgif.dl at Process Explorer.
                    Will we create release\imageformats folder?

                      Hi,

                      The deployment documentation "plugins chapter":https://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html#qt-plugins

                      explains that.
                      Basically you need to create the plugins folder and the needed subfolder like imageformats.

                      appfolder
                      appfolder\plugins
                      appfolder\plugins\imageformats
                      etc...

                      I've written a doc note with some examples about it but it has been on moderation for some time now and I can't access it.

                        yes, thanks for your solution . But it didnt' work , Will we NEED reconfigure something at .pro file?

                        After I add these folder.

                        *appfolder\plugins*
                        appfolder\plugins\accessible
                        appfolder\plugins\imageformats
                        appfolder\plugins\platforms
                        appfolder\plugins\sqldrivers

                        It didn't work. So that, I try with :

                        *appfolder\release\plugins*
                        appfolder\plugins\plugins\accessible
                        appfolder\plugins\plugins\mageformats
                        appfolder\plugins\plugins\platforms
                        appfolder\plugins\plugins\sqldrivers

                        It didn't work too.

                            The only exception is platform, it should be in appfolder directly so:

                            appfolder\plaftorms
                            appfolder\plugins\imageformats

                              @SGaist : Do you mean that we* will not* put platforms and plugins to RELEASE folder. Will We put these folder to appfolder?

                                    It's still didn't work. May you access my machine by teamviewer?.

                                    I replace all of them by :

                                    @appfolder
                                    appfolder\accessible
                                    appfolder\imageformats

                                      I put

                                      @appfolder\plugins
                                      appfolder\plugins\accessible
                                      appfolder\plugins\mageformats
                                      appfolder\plugins\platforms
                                      appfolder\plugins\sqldrivers@

                                      And write code:

                                      @int main(int argc, char *argv[])
                                      {
                                      qApp->addLibraryPath("../plugins");
                                      QApplication a(argc, argv);

                                      MainWindow w;
                                      w.show();
                                      
                                      return a.exec();
                                      

                                      }@ at main.cpp

                                      But it didnt' work. Just show "Microsoft Visual C++ runtime library".

                                        I make some basic project for testing. It work fine if we use images , but if when I use sqlite for connect. It shows error “Microsoft Visual C++ runtime library”. I think that because we didn't reconfig plugins. So that, It shows error.
