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

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：

如你所见，它在web.config之后删除了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.

这是我正在使用的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！
