我的问题是自我发现 and 纽尔方德从未设置为 true，因此我从未达到查看消息的条件已经更新 or 不降级
详细模式下“FindRelatedProduct”的结果：
MSI (c) (C0:F8) [08:43:46:624]：执行操作：FindRelatedProducts
操作 08:43:46：查找相关产品。搜索相关应用程序
行动开始 08:43:46：FindRelatedProducts。
操作结束于 08:43:46：FindRelatedProducts。返回值1。
MSI (s) (04:60) [08:43:55:263]：执行操作：FindRelatedProducts
操作 08:43:55：查找相关产品。搜索相关应用程序
行动开始 08:43:55：FindRelatedProducts。
MSI (s) (04:60) [08:43:55:263]：跳过 FindRelatedProducts 操作：已在客户端完成
操作于 08:43:55 结束：FindRelatedProducts。返回值0。
MSI (s) (04:60) [08:43:55:263]：跳过操作：已更新（条件为 false）
MSI (s) (04:60) [08:43:55:263]：跳过操作：NoDowngrade（条件为 false）
假设您的 UpgradeCode 指南和版本正确，您可能会跨上下文；每用户安装无法升级（或检测）每计算机安装，反之亦然。如果您使用详细日志进行安装，那么它可能会告诉您 FindRelatedProducts 在您的安装上下文中没有找到它。
