Question

这是我的情景：

使用Wix 3.6
使用WixUI_Advanced对话框设置（添加能够在安装期间控制各个功能的功能）
为NeverOverwrite="yes"组件设置web.config（以便安装后的本地更改不会丢失）

但是，安装程序似乎仍然在升级期间删除并重新安装web.config文件。

最好我可以告诉WixUI_Advanced对话框集具有以下配置：

<InstallExecuteSequence>
     <RemoveExistingProducts After="InstallInitialize"/>
</InstallExecuteSequence>

以下是安装中的日志片段：

如您所见，它会在web.config

之后删除InstallInitialize文件

当我尝试更改wxs文件时，添加：

<InstallExecuteSequence>
     <RemoveExistingProducts After="InstallFinalize"/>
</InstallExecuteSequence>

我明白了：

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.

以下是我使用的Product.wxs文件：

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部分。用户界面没有理由移动REP。

调度REP的默认值是在InstallValidate之后，这基本上是对旧产品的卸载，然后安装升级，所以它不是一个更新/覆盖配置文件的卸载/删除后再进行全新安装。

如果REP安装在AfterInstallExecute之后，则在升级期间会应用覆盖规则（因为升级＆＃34;覆盖＆＃34;卸载之前的现有已安装产品）。 web.config文件只需要在旧产品和新产品中具有相同的组件ID，如果在安装后确实已经更改，则覆盖规则应该意味着它不会被覆盖。

换句话说，只需使用带有afterInstallExecute的主要升级元素，在旧资源和新资源（文件等）中都有相同的组件ID，并且web.config文件不应被覆盖，并且你不会被覆盖。需要设置neveroverwrite。

在我看来，使用REP afterInstallExecute比InstallFinalize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，同时安装两个产品。如果旧产品的卸载失败，则在事务中使用REP会导致完全回滚。

如何在使用WixUI_Advanced时将RemoveExistingProducts更改为InstallFinalize之后？
