I had to reload Win 8.1 & NIS because of a failing HDD and would like to confirm that I am running the 64 bit version.
I noticed that the two instances of NIS in the Win Task Manager are both: Norton Internet Security (32bit)
File 'nis.exe' is in directory C:\Program Files (x86)\Norton Internet Security\Engine\22.5.5.15\
However, the directory C:\Program Files (x86)\Norton Internet Security\Engine64\22.5.5.15\ is populated with 51 files.
Thanks!
