    We have completed all required tasks for UWP final build. We have created build with failed certification report and after that we tried to install executable file, we got certification error. " Either a certificate must be installed for this app package or you need a new app package with trusted certificate" please suggest possible solution to our issue. Also see below error info :

    add-appxpackage : Deployment failed with HRESULT: 0x80073CF3, Package failed updates, dependency or conflict validation.
    Windows cannot install package COMPANY_NAME_GAME_NAMEXboxEdition_1.0.0.0_x64__rs8r5b65h5hnj because this package depends on a framework that could not be found. Trying to deploy appxbundle showing error.

    Please help asap related to above issue. We are building this file just for Xbox only Using UWP platform and in xbox live creator program.

    Please suggest possible solution.

    What do you mean by "failed certification report"? Do you mean it failed WACK (Certification test)? Is this failure from you own local testing or did it fail while trying to publish to Windows Store?

    From the error message, your app's certificate isn't trusted on Xbox, and similar to Windows, the certificate must be added to the Trusted Store before you can install the app (see StackOverflow post for general info on certificates).

    How are you deploying the app?
    - Visual Studio:
    - Xbox Device Portal:

    Have you successfully deploy your app to Xbox before? Is the Xbox console in "Developer Mode"? Just as with Windows you cannot install self-signed apps unless the OS is configured for developer mode (

    I recommend you also ask this question on the Microsoft developer forums (for Xbox) since this is a UWP specific problem.
