修改<！/强>
好的，进一步的检查和实验表明有问题的文件，即pathwaysMdf文件，正在安装！但是，在安装之后，它被RemoveFiles操作删除了！
我想这是因为该文件是原始安装的一部分，所以它正在执行卸载和清理工作。哎呀！我该怎么办？！
我仍然遇到这个问题。这是我最接近一个有效的解决方案，但它并没有完全奏效。这是（大部分）代码：

我遇到的问题是我需要数据库组件中的两个文件来替换以前的副本。由于这些文件是无版本的，我试图使用CompanionFile标记设置为PathwaysExe，因为它是应用程序的主要可执行文件，并且它正在更新，即使日志说它不是！最奇怪的是，PathwaysLdf文件正在更新正确，而PathwaysMdf文件不是。该日志似乎表明“现有文件具有相同的版本（使用随播版本检查）”。这很奇怪，因为该文件被替换得很好。
我唯一的想法是这个问题与安装顺序有关，我不知道如何继续！由于SettingsXml文件，我的InstallExecuteSequence设置与我一样，并且我不需要覆盖该文件，这实际上正在工作，因此无论数据库文件的解决方案是什么，都无法破坏工作设置文件！ ;）

请谢谢！

尝试RemoveExistingProducts的早期安排，而不是延迟安排，你应该没事。
<RemoveExistingProducts After="InstallInitialize" />
