ClickOnce Deployment Auto Update Does Not Work

I am using ClickOnce deployment to check for updates:

  • I made the settings, both on the publication tab, published the URL and checked the update path, and checked for updates before launching the application and launching the application both offline and on the Internet.
  • I get updates if you install the application from the local system, but if I install the application from the server, it does not check for updates.

Below is the code I used to check for updates. How to fix this problem?

private void InstallUpdateSyncWithInfo()
{
    UpdateCheckInfo info = null;
    if (ApplicationDeployment.IsNetworkDeployed)
    {
        ApplicationDeployment ad = ApplicationDeployment.CurrentDeployment;

        try
        {
            info = ad.CheckForDetailedUpdate();
        }
        catch (DeploymentDownloadException dde)
        {
            MessageBox.Show("The new version of the application cannot be downloaded at this time. \n\nPlease check your network connection, or try again later. Error: " + dde.Message);
            return;
        }
        catch (InvalidDeploymentException ide)
        {
            MessageBox.Show("Cannot check for a new version of the application. The ClickOnce deployment is corrupt. Please redeploy the application and try again. Error: " + ide.Message);
            return;
        }
        catch (InvalidOperationException ioe)
        {
            MessageBox.Show("This application cannot be updated. It is likely not a ClickOnce application. Error: " + ioe.Message);
            return;
        }

        if (info.UpdateAvailable)
        {
            Boolean doUpdate = true;

            if (!info.IsUpdateRequired)
            {
                DialogResult dr = MessageBox.Show("An update is available. Would you like to update the application now?", "Update Available", MessageBoxButtons.OKCancel);
                if (!(DialogResult.OK == dr))
                {
                    doUpdate = false;
                }
            }
            else
            {
                // Display a message that the app MUST reboot. Display the minimum required version.
                MessageBox.Show("This application has detected a mandatory update from your current " +
                    "version to version " + info.MinimumRequiredVersion.ToString() +
                    ". The application will now install the update and restart.",
                    "Update Available", MessageBoxButtons.OK,
                    MessageBoxIcon.Information);
            }

            if (doUpdate)
            {
                try
                {
                    ad.Update();
                    MessageBox.Show("The application has been upgraded, and will now restart.");
                    Application.Restart();

                }
                catch (DeploymentDownloadException dde)
                {
                    MessageBox.Show("Cannot install the latest version of the application. \n\nPlease check your network connection, or try again later. Error: " + dde);
                    return;
                }
            }
        }
    }
    else
    {
        MessageBox.Show("There are no updates available");
    }
}
