wix - 安装过程中关于 InstallLevel 和条件的奇怪可重现行为

Question

我创建了一个复制 4 个文件的 MSI 安装程序。功能的安装级别为 1。如果存在必要的文件，则安装级别应为 0。我想避免文件被安装程序覆盖。所以我多次运行安装程序，这发生了

#1：安装程序复制 4 个文件。在日志文件中，安装级别为 1

#2：我删除了一个不必要的文件并再次运行安装程序。安装程序复制所有 4 个文件。在日志文件中，安装级别为 1

#3：我删除了一个不必要的文件并再次运行安装程序。没有文件被复制，但日志文件显示安装级别为 1

#4 - #n：与步骤 3 相同

#n+1：我删除了必要的文件，安装程序复制了文件。现在它像#1 和#2 一样开始。

在日志文件中，安装级别始终为 1，即使文件是否被复制。我无法解释它，在我理解问题之前我不想在生产中使用它。

您可能会看到我没有看到的问题（我已经替换了一些 GUID）：
