C# 尽管WIX安装失败，Word加载项仍会安装

使用WIX工具集v3.10.3.3007创建安装程序以安装MS Word加载项。如何确保故障进行完全回滚

我正在向WIX对话框序列中注入一个自定义操作，以检查用户输入的值。如果检查失败，我希望安装失败我有明确触发故障的条件，但即使触发了故障，外接程序仍会安装并运行。故意故障会弹出预期对话框，说明：

..安装向导因错误而提前结束。您的系统尚未修改

除此之外，我的系统已被修改。以下是我认为你需要看到的。我是一名WIX新手，因此我不确定是否遗漏了相关内容：

自定义操作：

using System;
using Microsoft.Deployment.WindowsInstaller;

namespace RegisterAddIn
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult RegisterAddIn(Session session)
        {
            try
            {
                session.Log("Begin CustomAction1");
                string token = session["ActivationToken"];

                if (token == null)
                {
                    throw new Exception("No token set yet");
                }

                if (token == "fail it")
                {
                    return ActionResult.Failure;
                }

                session.Log("Captured activation token = " + session["ActivationToken"]);
                return ActionResult.Success;
            }
            catch (Exception e)
            {
                session.Log(e.Message);
                return ActionResult.Failure;
            }    
        }
    }
}

通常故障会回滚当前安装，我在PowerPoint加载项中体验到了这一点。确保回滚执行的最简单方法是（刷新）查看控制面板中的程序和功能列表。如果您的应用程序列在那里，则表示没有发生回滚。你能确认一下吗？我能确认它在那里。我一直在卸载它从那里反复，因为我试图找出问题。文档说明应该发生回滚，最后的对话框说“系统尚未修改”，所以我不明白。这将使强制支付注册密钥变得困难。我明白了。尝试使用这些值。它对我很有效。在WixUI_InstallDir.wxs中，将值Execute=“immediate”替换为“deffered”。在“产品：*”一节中，未解析对符号“WixAction:InstallUISequence/InstallFinalize”的引用。我将尝试在自定义对话框中执行自定义操作，而不是安排它，然后看看它是如何进行的。糟糕的是，我没有要求将标记替换为其他建议。我认为在一开始使用Wix工具集是很困难的，但随着时间的推移，它是最好的Windows installer框架之一，它为您在线/离线设计、开发和部署软件包提供了最大的灵活性。
