Parsing icon for applications issue

Cobra91151

I want to get applications icon from the registry. The problem is that I'm getting only default application icon. How to get the actual application icon? Thanks.

Code:

   QStringList allLocalMachineX86Keys;
   QString displayIcon;
   QString iconFile;
   QIcon programIcon;
   QStringList displayIconSplitted;
   QString iconSplittedData;
   QFileIconProvider fileIconProvider;
   QString displayName;

QSettings registryKeyLocalMachineX86("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall", QSettings::NativeFormat);
        allLocalMachineX86Keys = registryKeyLocalMachineX86.allKeys();

        for (QString key : allLocalMachineX86Keys) {
            if (!key.isEmpty()) {
                if (key.contains("DisplayIcon")) {
                    displayIcon = registryKeyLocalMachineX86.value(key).toString();

                    if (displayIcon.contains("\"")) {
                        displayIconSplitted = displayIcon.split("\"");
                        iconSplittedData = displayIconSplitted.value(displayIconSplitted.length() - 2);
                        iconFile = iconSplittedData;
                    } else if (displayIcon.contains(",")) {
                        displayIconSplitted = displayIcon.split(",");
                        iconSplittedData = displayIconSplitted.value(displayIconSplitted.length() - 2);
                        iconFile = iconSplittedData;
                    } else {
                        iconFile = displayIcon;
                    }

                    if (iconFile.contains(".ico")) {
                        programIcon = QIcon(iconFile);
                    } else {
                        QFileInfo fileInfo(iconFile);
                        programIcon = fileIconProvider.icon(fileInfo);
                    }
                } else {
                    programIcon = QtWin::fromHICON(LoadIcon(NULL, IDI_APPLICATION));
                }

                if (key.contains("DisplayName") && registryKeyLocalMachineX86.value(key).toString() != "") {
                    displayName = registryKeyLocalMachineX86.value(key).toString();
                    emit appData(programIcon, displayName);
                }
        }
   }

Update:
When I have commented these lines of code:

//else {
       //programIcon = QtWin::fromHICON(LoadIcon(NULL, IDI_APPLICATION));
     // }

the apps icon displays but some are empty or not from the application (image below):

Anyone know how to fix it? Thanks in advance.
