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 an.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它们将被删除，除非用户再次明确检查它们是否安装。

无论如何，每次安装新版本时，.msi 是否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，只有当您确实想要对您的产品进行重大更新时，它才有意义，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标记下方的MigrateFeatureStates操作仅次要。

如果没有MigrateFeatures="yes"属性（隐式或显式），则不会执行此操作，如上所述。

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

如果要调整执行顺序中的操作的 position，您只需要在InstallExecuteSequence标记中显式定义MigrateFeatureStates操作。

Answer 2

尝试使用MajorUpgrade标记。

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