Wix 升级 msi 删除已安装的功能

Question

I am using the Wix Toolset to generate an.msi for my application. Everything works when I upgrade to a new version, except every time I run a newer version installation the setup doesn't detect already installed features and instead defaults to the features that are 'required' which means if the user installed any of the other features they are removed unless the user explicitly checks them for installation again.

Is there anyway to have the.msi detect which features are currently installed each time a newer version is installed?

Answer 1

@dpb's answer would solve the problem, because the MajorUpgrade tag has a MigrateFeatures attribute with an implicit default value of yes . However, it is only relevant if you actually want to create a major update to your product, which has implications. - This is not an option for me.

If you do not want to perform a major update, you must add the MigrateFeatures attribute to the UpgradeVersion tag and explicitly set it's value to yes .

---

The MigrateFeatureStates action below the InstallExecuteSequence tag is of minor importance only.

This action will not be executed if there is no MigrateFeatures="yes" attribute (implicit or explicit), as described above.

If there is a MigrateFeatures="yes" attribute, the MigrateFeatureStates action will automatically be added to the InstallExecuteSequence table of the installer.

You only need to explicitly define the MigrateFeatureStates action in the InstallExecuteSequence tag, if you want to adjust the action's position in the execution sequence.

Answer 2

Try using MajorUpgrade tag.

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