    Hi TsangTakKit,

    It seems that the error is caused by missing cab file that is treated as unsigned. Or it is signed actually, but is published with an old certificate. If so, I suggest that you send a feedback to Microsoft Product Team on Developer Community and get the book with a new signature.

    By the way, the Visual Studio 2012 is an old version, we recommend you use a newer version of Visual Studio(VS2017 or VS2019) to start your work.

    Best regards,
    Anna
