windows – WiX,如何防止文件卸载虽然我们忘了设置Permanent =“yes”

我们有一个使用Wix创建的产品安装程序,其中包含程序包(“V1”)和一些配置文件.现在,我们将使用新的产品代码进行重大升级,其中卸载了旧版本的产品并安装了“V2”.我们想要的是保存其中一个配置文件免于卸载,因为它也需要V2.不幸的是,当我们发送V1( read this question以获取更多信息)时,我们忘记设置Permanent =“yes”选项.

这里有一个问题：是否有一种简单的方法可以防止文件的卸载？当然,我们可以在脚本中添加一个自定义操作来在卸载之前备份文件,然后再添加另一个自定义操作来恢复它,但恕我直言,这个任务似乎有点过分,并且可能会干扰MSI注册过程的其他部分.

编辑：是的,NeverOverwrite =“yes”属性已经在V2中设置,行为就像我描述的那样.

我不认为在V2的组件参数中直接更改某些内容会有所帮助.也许有机会在卸载V1之前以某种方式在自定义操作中修改注册表,以便安装程序服务认为V1中的配置文件是使用Permanent =“yes”安装的？

尝试配置文件的NeverOverwrite属性

If this attribute is set to ‘yes’,the
installer does not install or
reinstall the component if a key path
file or a key path registry entry for
the component already exists.

编辑

我刚刚在测试设置中对此进行了测试.起初它没有用,因为我在InstallInitialize序列之前安排了RemoveExistingProducts操作.这会在安装新产品之前删除旧产品,因此无法进行比较.

但是,当我将它设置为InstallFinalize后,它确实有效,即使原始设置没有设置NeverOverwrite,它也会将文件保留在那里.这是我的两个测试示例
