win 8.1 64+nort prem 360-shows 32 bit-is this product even working on my computer?

i have windows 8.1 64 bit, and norton premiere 360, which shows as 32 bit when i see file names etc..  is this product even working on my computer?  when i search norton store for windows 8.1 64, it shows, "nothing found".

 

have had norton since i first got a computer in 2008.  this computer is also hp laptop, and was upgraded to 8.1 about a month ago <sigh>

 

thanks for any information
