Help Please!

Hello everyone! I need some help c:

I have recently purchased Norton AntiVirus for 3 PCs. I downlaoded the product onto my PC, and, unfortunately, I am not able to download it on the other two PCs.
I've tried the following: on one of the PCs, I've accessed my Norton account, and tried to download it from there, but my order does not appear under 'Products.'
On the other hand, I can see my order under 'Order History.'

So, to sum it up, I can't download my product on my other computers because it's not under 'Products,' and I generally can't find a 'download' button anywhere.
