Hi darron.harvey.dh,

Sorry for our late response.

You can first activate the serial number from the link below:
https://mobilesecurity.trendmicro.com/utility/activation/enter_ak

It will allow you to create your own Trend Micro account and then provide you further instructions on how to activate the app.

Let us know if you need further assistance. Thanks!
