administrative privileges issue when using VTune Amplifier

Hi,

            I  am trying to use VTune Amplifier with demo project tachyon_vtune_amp_xe.zip in C:\Program Files (x86)\Intel\VTune Amplifier XE 2015\samples\en\C++, but not sure why it reports below issue, so look for help here

             It says:  Collection failed.The data cannot be displayed.  Highly accurate CPU time collection is disabled for this analysis.To enable this feature, run the product with the administrative privileges.  [Instrumentation Engine]: SYSCALL_INSPECTOR:Too long trace in the NTDLL!NtSetContextThread function.

             I am using it on windows 7, I installed below tools:

                              vistual studio 2013,

                              intel parallel studio XE 2015

                             MKL

                             IPP

Thank you

John
