There isn't enough information here to provide much help. Any installation failure of an appx/msix/bundle is logged in the event log Microsoft\Windows\AppXPackagingOM\Operational log. This would usually contain ane event that points out the line of the appxmanifest generating the error and why. You might need to package using "full trust".

    I did not say you need this, but only that you might.  Read the error to know what is wrong and fix the manifest appropriately.

     

    If full trust is needed, in the manifest, you need to first set the capability like this,

     

        <Capabilities>
        <rescap:Capability Name="runFullTrust" />
        ...
    </Capabilities>

     

     which is what starts the container to allow for msix.  Then on the application,

     

        <Applications>
        <Application Id="XXX" Executable="YYY.exe" EntryPoint="Windows.FullTrustApplication">
            ...
        </Application>
        ...
    </Applications

     

    which makes the application run using full trust (which really means more trust than AppX gets).

     

    rescap, aka "restrictedcapabilities" must also be added to the schema list on the <Package> element.
