Wix 升级 msi 删除已安装的功能

Question

我正在使用 Wix 工具集为我的应用程序生成 .msi。当我升级到新版本时一切正常，除了每次我运行更新版本安装时，安装程​​序不会检测已安装的功能，而是默认为“必需”的功能，这意味着如果用户安装了任何其他功能除非用户再次明确检查它们是否安装，否则它们将被删除。

每次安装较新版本时，是否让 .msi 检测当前安装了哪些功能？

Answer 1

@dpb 的回答可以解决问题，因为MajorUpgrade 标记有一个MigrateFeatures 属性，其隐式默认值为yes。 但是，仅当您确实想为您的产品创建 major update 时才相关，这会产生影响。 - 这不是我的选择。

如果您不想执行重大更新，则必须将MigrateFeatures 属性添加到UpgradeVersion 标记并将其值明确设置为yes。

InstallExecuteSequence 标签下方的MigrateFeatureStates action 只是次要的。

如上所述，如果没有MigrateFeatures="yes" 属性（隐式或显式），则此操作将不执行。

如果有MigrateFeatures="yes" 属性，MigrateFeatureStates 操作将自动添加到安装程序的 InstallExecuteSequence 表中。

如果要调整动作在执行顺序中的位置，只需在InstallExecuteSequence标签中显式定义MigrateFeatureStates动作即可。

Answer 2

尝试使用MajorUpgrade 标签。

`<MajorUpgrade DowngradeErrorMessage="Can’t downgrade." />`
