Cannot deploy UWP app with ms-appinstaller

Question

I created my UWP app package, but ms-appinstaller shows me error when I try to install.

"Error in parsing the app package.", all files can be downloaded via browser

ms-appinstaller file:

    </Dependencies>
    <UpdateSettings>
        <OnLaunch

    </UpdateSettings>
</AppInstaller>

If I run .msix, then it install my app successfully.

(right window shows what my app already installed 'cause I installed it with .msix before my question)

upd1:

I set mime types , but this don't work
