Wix Custom BA 妥善处理升级

Question

几天来，我一直在与 Wix 自定义 Bootstrap 作斗争，试图让升级正常工作。 BA 升级代码保持不变，而 MSI 文件具有新的产品代码。我只在 ARP 中显示 BA，不显示 MSI。我已经知道它可以正确升级所有 MSI 文件，但是当它结束并打开旧包以卸载它时，它会打开并执行，但 ARP 中的条目仍然存在，所以现在我有两个。

这是完整的代码(减去一些 GUI 特定代码):

Answer 1

我终于明白了!正如所怀疑的那样，它是一些小东西。这完全取决于时机。

第一个问题是我需要在 DetectComplete 操作中执行计划卸载:

   private void OnDetectComplete(object sender, DetectCompleteEventArgs e)
   {
       if (Bootstrapper.Command.Action == LaunchAction.Uninstall && Bootstrapper.Command.Display == Display.Embedded)
       {
           Bootstrapper.Engine.Plan(LaunchAction.Uninstall);
       }
   }

那么卸载旧包的日志被缩短的原因是我过早退出了应用程序。我将其移至 ApplyComplete 操作:

    private void OnApplyComplete(object sender, ApplyCompleteEventArgs e)
    {
        if (Bootstrapper.Command.Action == LaunchAction.Uninstall && Bootstrapper.Command.Display == Display.Embedded) {
            //Uninstalling the old bootstrapper
            Bootstrapper.Engine.Quit(0);
            Environment.Exit(0);
        }
    }
