bre*_*ker 1 windows-installer wix
这是我的场景：
WixUI_Advanced对话框集（添加能够在安装过程中控制单个功能的能力）NeverOverwrite="yes"一个web.config组件（这样的局部变化，安装后不会丢失）但是，安装程序web.config在升级过程中似乎仍会删除并重新安装该文件。
最好我可以告诉WixUI_Advanced对话框集配置如下：
<InstallExecuteSequence>
<RemoveExistingProducts After="InstallInitialize"/>
</InstallExecuteSequence>
以下是安装的日志片段：

如您所见，它会在web.config之后删除文件InstallInitialize

我得到：
error LGHT0091: Duplicate symbol 'WixAction:InstallExecuteSequence/RemoveExistingProducts' found. This typically means that an Id is duplicated. Check to make sure all your identifiers of a given type (File, Component, Feature) are unique.
这是Product.wxs我正在使用的文件：
<InstallExecuteSequence>
<RemoveExistingProducts After="InstallFinalize"/>
</InstallExecuteSequence>
如何在 InstallFinalize 之后更改 RemoveExistingProducts？最终，我只需要这个文件永远不会被覆盖。
谢谢！
MajorUpgrade 标记是进行升级的首选方式，它将在您指定的任何地方对 RemoveExistingProducts (REP) 进行排序 - 这应该简化其中的一些。UI 没有理由移动 REP。
调度 REP 的默认设置是在 InstallValidate 之后，这基本上是卸载旧产品，然后安装升级，因此与其说是更新/覆盖配置文件，不如说是卸载/删除，然后是全新安装。
如果 REP 安排在 InstallExecute 之后，则在升级期间应用覆盖规则（因为升级会在卸载之前“覆盖”现有的已安装产品）。web.config 文件只需要在旧产品和新产品中具有相同的组件 ID，如果它在安装后确实发生了更改，那么覆盖规则应该意味着它不会被覆盖。

换句话说，只需将主要升级元素与 afterInstallExecute 一起使用，在新旧资源（文件等）中具有相同的组件 ID，并且不应覆盖 web.config 文件，并且您不需要设置 neveroverwrite。
在我看来，在InstallExecute 之后使用REP 比在InstallFinalize 之后更好，因为后者在安装事务之外，因此升级安装可以成功，然后InstallFinalize 之后的REP 可能会失败并回滚，从而使两个产品同时安装。如果旧产品的卸载失败，在事务中使用 REP 会导致完全回滚。
