我正在尝试使用 WIX 创建一个 MSI，我似乎偶然发现了一个小问题，这让我在升级方面有点困惑。我已经关注了大约 3 个关于该主题的教程，每个教程都给了我相同的结果。当我尝试升级应用程序时，我得到了一个通用的

该产品的另一个版本已安装。

信息。环顾四周后，我发现为了成功升级，我需要指定一个新的产品 G​​UID。这对我来说似乎很奇怪，因为主要的 WiX 网站说只有主要安装才需要这样做。由于我运气不佳，我决定继续使用它。瞧，它成功执行了安装程序，但是当我签入添加/删除程序时，我现在安装了 2 个应用程序副本。这真让我抓狂。请参阅下面的 .wxs，并在适用的情况下向我展示我的错误。

将 Product/@Id 设置为“*”以获取自动产品代码更改并使用MajorUpgrade 元素。有关更多上下文，请参阅我的博客。
