Consider a package with a manifest including:

<Package...>

      <Applications>

          ...

       </Applications>

        <Extensions/>

</Package>

 

This package creates OK using makemsix, but will fail to install using the AppInstaller on 20h2 (did not try other versions, but presumably the same).

 

Removing the <Extensions/> line solves this issue.  As with other cases that I have documented, AppInstaller should not reject legal packages.

Hi @TIMOTHY MANGAN, Can you file a Feedback for this via the Feedback hub? Can you tell us what is the failure message you get with App Installer?
