Can't Install a Product without Automatic Renewal

Hello,

I've bought a Norton Security for 3 devices.

The first download to my primary device went OK.

I'm now trying to download to my secondary device, a tablet. The problem is that I can not get beyond the Automatic Renewal prompt. I skip the Automatic renewal prompt, enter the Product Code as requested and then get returned to the original Automatic Renewal menu.

How can I get Norton to accept the Product code. Its a Norton produced product.

Regards
