new certificate must be installed for this app package RRS feed

  • Question

  • I am trying to package a CDA using Visual Studio Desktop Bridge. Everything works as it should with Visual Studio 2017 update 4, the package is created. When I sideload the app to either my windows surface or laptop both windows 10 I get the following error.

    Either a new certificate must be installed for this app package or you need a new app package with trusted certificates. Your system administrator or the app developer can help. A certificate chain was processed but terminated in a root certificate that isn't trusted (0x800B0109)

  • Hi Terry,

    According to the error message, you need to install the certificate file that is used to sign your package on your machine. After that, you will be able to sideload your package on that device.

    You might follow the steps below to install the certificate.

    Double click the certificate file in the app package folder:

    Click the install button, choose local machine and click next.

    Open the certificate Store and select trusted people:

    Click Ok and Next to finish the installation.

    Then that error will not persist.

    Best regards,

    Hi Bob

     

    Thanks for the help neither of those two links worked. Just some informative feedback those links were rather vague and cryptic. Could you please help me without links as Roy Li did.

  • Hi,

    By default, all app packages that Visual Studio generates are signed with a test certificate.

    The certificate must be installed on the machine before the app package is installed.

    Check this Docs:https://msdn.microsoft.com/en-us/library/windows/desktop/br230260(v=vs.85).aspx

    So try to install certificate,steps see following post.

  • Some people are complaining that the response from Mattew Wu is not working. I liked his response. It worked well for me except that in his wizard I chose the root trusted certificates in the Certificate Store as explained here, as well.

    Thank you Mathew Wu for helping me. EXCELLENT response.
