      @Ijon_Tichi Usually resources are built into the executable, so it should work. See "Compiled-In Resources" in https://doc.qt.io/qt-5/resources.html
      Can you show how you're using your resources?
      Also, do you see any warnings when you start your app from cmd.exe?

        hello jsulm

        i use a *.qrc (jack-ressourcen.qrc) over the Qt Creator
        <RCC>
        <qresource prefix="/images">
        <file>ressourcen/jack-logo.jpg</file>
        <file>ressourcen/Startbild.jpg</file>
        <file>ressourcen/JACK-mittel.jpg</file>
        <file>ressourcen/JACK-groß.jpg</file>
        </qresource>
        </RCC>

        in the source code i use the ressources

        ...
        QImage imageLogo(":/images/ressourcen/jack-logo.jpg","JPG");
        ...
        ui->label_imageLogo->setPixmap(QPixmap::fromImage(imageLogo));
        ...

        When i rum with Qt Creator (debug or relase) it works the imageLogo is displayed.

        Whan i run from cmd.exe there ist no error, the program works, but the imageLogo is not shown.

        A image, that i generate by QPainter thru the Program is shown, there no problem running from CMD :
        ...
        QImage imageSchablone(2480, 3508, QImage::Format_RGB32);
        ...
        // calculating the image
        imageSchablone = aktSchablone.berechnen(aktuellerTonarm);
        ....
        // show the image
        // PixMapSchablone is a lable on the ui
        ui->PixMapSchablone->setPixmap( QPixmap::fromImage(imageSchablone).scaledToHeight(900));
        ...

          I have testet with aditional images in the QRessource System.
          The progam.exe get bigger, so i think the images are link into the program.

          ... but the the images are not shown when i rum from cmd.exe

              @Ijon_Tichi I think your problem is that you do not deploy your app properly before starting outside of QtCreator, so it can't find needed plug-in.
              See https://doc.qt.io/qt-5/windows-deployment.html

                thanks jsulm,
                yes, i readed this many time but i unterstand it not full, i am a beginner in Qt.
                The windeployqt doesn't tell what plug-ins is needed.
                Even when i copy all plug-ins folders into the working directory my jpg-files are not loaded.
                Maybe there is a format problem to my jpg-files

                I think, i have the needed plug-in to handle jpg, all I/O opterations (store, ..) with jpg that are calculated by the program works.

                Wenn i use *.png images in the QRessource System it works fine, even from cmd.exe
                So i have changed to the *.png format.

                to me it is all fine, further i use png format

                thanks jsulm to your help

                Ijon

                  @Ijon_Tichi So, did you actually use windeployqt tool? It should copy the plug-in. Also, the plugins need to bi in a subdirectory as shown in the above link in an example:

                  The executable	plugandpaint.exe
                  The Basic Tools plugin	plugins\pnp_basictools.dll
                  The ExtraFilters plugin	plugins\pnp_extrafilters.dll
                  The Qt Windows platform plugin	platforms\qwindows.dll
                  The Qt Windows Vista style plugin	styles\qwindowsvistastyle.dll
                  The Qt Core module	Qt5Core.dll
                  The Qt GUI module	Qt5Gui.dll
                  The Qt Widgets module	Qt5Widgets.dll

                    as i wrote in Post 1

                    i put

                    libgcc_s_seh-1.dll 
                    libstdc++-6.dll 
                    libwinpthread-1.dll
                    Qt5Core.dll 
                    Qt5Gui.dll 
                    Qt5Widgets.dll
                    

                    and the plugin folders

                    imageformats
                    platforms
                    printsupport
                    styles
                    

                    into the working directory.

                    but even when i copy all plug-in folders into the working directory there is the trouble with the jpg.

                    where can i find information, what plug-ins more than "imageformats" are needed to handle jpg?

                    as i wrote in post 2 i use the windeployqt tool, i have set the env (qtenv2.bat) bevor:

                    windeployqt Output:

                    D:\QT-Creator-Projekte\build-JACK-Tool-Desktop_Qt_5_14_0_MinGW_64_bit-Release>windeployqt --release JACK-Tool.exe
                    D:\QT-Creator-Projekte\build-JACK-Tool-Desktop_Qt_5_14_0_MinGW_64_bit-Release\JACK-Tool.exe 64 bit, release executable

                    To be deployed : Qt5Core Qt5Gui Qt5Widgets
                    Unable to find the platform plugin.
                    

                    searching to the error message "Unable to find the platform plugin", i doesn't found a solution

                    I thing the ressource system work fine. By using png format it works fine.

                      @Ijon_Tichi said in How to deploy when using Resource System? (Windows 10):

                      Unable to find the platform plugin.

                      To solve the problem with the windeployqt i downloaded the windeployqt64releaseonly.exe from here: http://tripleboot.org/Uploads/windeployqt64releaseonly.zip
