How to install bit defender total security in 3rd device

I purchased Bitdefender TOTAL Security from Amazon. It was for 3 devices and 3 years. I was given a activation code. Through this code, I installed in two computers. I could not install it in 3rd device in my one of the desktop computer.

Kindly solve the issue at the earliest.
