Dear K.Ping
This is because of the unsuccessful unpack of the content package krub.
This content package is a file name “NielsenAnswer_update.NCPF” krub.
K.Ping can either use the aforementioned file from any prior email send by Nielsen team or as attached in this email krub and follow the step in “Unpack Content Package.pdf” krub.
However, after reinstall of the content package and the problem still persist, please feel free to contact us krub.
Best Regards,
