Qt Installer Framework creating multiple entries in Windows Add or Remove Programs

Allstar12345

Hi guys,

I have a punched together Qt Installer Framework for my Windows App, it all installs fine and overwrites fine when I update the App but it creates a new entry in the Windows Add or remove programs list on every install; I guess it thinks it's installing a clean copy instead of a replacement.

This is my installer script:

var targetDirectoryPage = null;


function Component()
{
    installer.gainAdminRights();
    component.loaded.connect(this, this.installerLoaded);
    installer.setDefaultPageVisible(QInstaller.ComponentSelection, false);
}

Component.prototype.createOperations = function()
{
    component.createOperations();

    if (systemInfo.productType === "windows") {
        component.addOperation("CreateShortcut", "@TargetDir@/sRadioWindows.exe","@AllUsersStartMenuProgramsPath@/sRadio.lnk",
            "workingDirectory=@TargetDir@", "iconPath=@TargetDir@/icon.ico",
            "iconId=2", "description=sRadio Executable");
    }
}


Component.prototype.installerLoaded = function()
{
    installer.setDefaultPageVisible(QInstaller.TargetDirectory, false);
    installer.addWizardPage(component, "TargetWidget", QInstaller.TargetDirectory);
    targetDirectoryPage = gui.pageWidgetByObjectName("DynamicTargetWidget");
    targetDirectoryPage.windowTitle = "Choose Installation Directory";
    targetDirectoryPage.description.setText("Please select where the sRadio will be installed:");
    targetDirectoryPage.targetDirectory.textChanged.connect(this, this.targetDirectoryChanged);
    targetDirectoryPage.targetDirectory.setText(installer.value("TargetDir"));
    targetDirectoryPage.targetChooser.released.connect(this, this.targetChooserClicked);
    gui.pageById(QInstaller.ComponentSelection).entered.connect(this, this.componentSelectionPageEntered);
}

Component.prototype.targetChooserClicked = function()
{
    var dir = QFileDialog.getExistingDirectory("", targetDirectoryPage.targetDirectory.text);
    targetDirectoryPage.targetDirectory.setText(dir);
}

Component.prototype.targetDirectoryChanged = function()
{
    var dir = targetDirectoryPage.targetDirectory.text;
    if (installer.fileExists(dir) && installer.fileExists(dir + "/maintenancetool.exe")) {
        targetDirectoryPage.warning.setText("<p style=\"color: red\">Existing installation detected and will be overwritten.</p>");
    }
    else if (installer.fileExists(dir)) {
        targetDirectoryPage.warning.setText("<p style=\"color: red\">Installing in existing directory. It will be wiped on uninstallation.</p>");
    }
    else {
        targetDirectoryPage.warning.setText("");
    }
    installer.setValue("TargetDir", dir);
}


Component.prototype.componentSelectionPageEntered = function()
{
    var dir = installer.value("TargetDir");
    if (installer.fileExists(dir) && installer.fileExists(dir + "/maintenancetool.exe")) {
        installer.execute(dir + "/maintenancetool.exe", "--script=" + dir + "/scripts/auto_uninstall.qs");
    }
}

Config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
    <Name>sRadio</Name>
    <Version>1.1.0</Version>
    <Title>sRadio</Title>

    <StartMenuDir>sRadio</StartMenuDir>
    <TargetDir>@ApplicationsDir@/AllstarSoftware/sRadio</TargetDir>
    <RepositorySettingsPageVisible>false</RepositorySettingsPageVisible>
</Installer>

Package.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Package>
    <DisplayName>sRadio</DisplayName>
    <Description>sRadio SHOUTcast Internet radio client</Description>
    <Version>1.1.0-0</Version>

    <Default>true</Default>
    <Required>true</Required>
    <Script>installscript.qs</Script>
    <UserInterfaces>
           <UserInterface>targetwidget.ui</UserInterface>
       </UserInterfaces>
</Package>

Does anyone know how to prevent it creating a new entry every time?

Thanks.

I have the same problem. Did you solve this problem?

No, I ended up creating my own custom in-App updater that just replaces the files changed where necessary, it's not ideal by any means but it's better than this.

I have the same problem too. Somebody found solution ?
it looks as installer generate new appId when started. How we can freeze appId for our application.
