Installation of NPL failed error

Hi ,

Please, can anybody let me know how to check this log files so that I can find the reason for installation failure.

I have downloaded ABAP 7.51SP02(Since SP01 has licence expired issue) still not able to installed.

I am using Win10..and installing ABAP on Oracle Virtualbox.
