Question

WiX is shipped with some UI options. I created a test project to try upgrade.

I use Mondo UI for this matter. The upgrade runs fine, the question is, the UI does not react to it as upgrade but as plain installation. I don't know if upgrade has supported UI or not and this is mainly the question:

Is it supported or am I missing something?

Was it helpful?

Solution

Try to add your own chain of dialogs. For example:

<Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg" Order="20">
            ( Installed AND (PATCH OR REINSTALL ) ) OR WIX_UPGRADE_DETECTED
          </Publish>
<Publish Dialog="VerifyReadyDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg">REINSTALL OR WIX_UPGRADE_DETECTED</Publish>
