I hope this is the right place to put this, sorry if its not!

On Server 2012, I added a Windows 8.1 KMS B key to the Product Keys node in VAMT 3.0.  I then go to the Active Directory Based Activation "Online Activate Forest", choose the Key, the object name becomes:

"Win 8.1 RTM Enterprise;EnterpriseN;Professional;ProfessionalN Volume:CSVLK"

I hit Install key and after a wait, it fails with 0xC004F050

I looked it up.. it seems to mean that its an invalid key... I have seen that error with Server 2008R2 that needed a hotfix, but not with Server 2012!

I was able to put Office 2013 Volume license pack on the same server and get the key into AD, did I screw something up by doing that first?

Any ideas?  I'm not sure what to try next

Apparently an update is needed on Server 2012R2..

I installed Windows8-RT-KB2885698.msu (64bit) and it started working.
