Activating virtual servers on hyper-v 2012 R2

Hi all,

I purchased two windows server 2012 R2 standard edition licenses. I downloaded and install the evaluation and then activated using the licenses I purchased. No problems there.

as I understand with windows server 2012 R2 standard edition, I should get to install 2 virtual servers free of charge, which I have done so already on each server using hyper-v, except I am not able to activate them as of yet.

so how should this be done or how can I activate those VMs or what's the correct way to do it without having to purchase 4 additional licenses?

Thanks in advance
