the instructions on my f-secure product code doesn't work they seem outdated the box says i should go to f-secure.com/box but that site isnt there
Assuming this is F-Secure SAFE, you need to register on the SAFE Portal, then I think you can go to Accounts and Payments within that portal, and you should see a link to enter a code.
If this isn't F-Secure SAFE, then please let us know which product you are referring to.
Also... in fact.. there should be re-direction (this is work with my browser about your link) to next link:
When you registered there (under current link-url).
WIth login.. you will be prompted to add your license-subscription-information (as activation step).
Or can be work direct link for registration:
https://mysafe.f-secure.com/register/box/******-******-******-****** (where the "******-******-******-******" is your subscription-license).
With other (F-Secure IS?!) possible can be same step. You able to get installer from "Downloads" under F-Secure web-site and will add subscription-license for installer-name (or by ask it?!).
Sorry for reply.
