Licensing a Guest VM on Hyper V 2012 R2

Good Morning Experts,

I am having trouble licensing a new VM I created on our new Hyper V server.

We purchased 2012 R2 Datacenter so we could license all the guest VM's but how to activate them is confusing me.

I have done some research and came across this:
slmgr.vbs /ipk <AVMA_Client_Key>
I ran this with the appropriate code and it comes up with an error.  When I evaluate the error it says the code is wrong.

Am I suppose to license it with our DataCenter code or build a kms with our Datacenter code?

So confused, thank you for your help.

A key is not a license.  The good news is if you have data center, you are licensed.  Getting the key installed is another matter.  

They keys you use are as follows:

Do NOT use your key.  If you have further errors, please post screen shots - you shouldn't be posting anything private since the keys above are publicly available.

That's the one I tried and I get a error.  I tried multiple times and the same result.  I didn't try my own yet and I wouldn't post it.  I will do it again and post the screen shots.

Here is the error I get after running that code.

Can you visually verify that you installed 2012 R2 (that R2 is important) datacenter in both the host and guest? Only datacenter supports automatic VM activation (Aka AVMA)

WELL!  Guess what just activated once I took a closer look and realized it wasn't R2!  I upgraded to R2 (this is a test Vm and nothing installed on it yet) and re ran the code.  Said it was successful.  Thank you so much!
