OK, just have installed 9471 and Off2013, downloaded KMS K20 and try to activate, Result: 25 try = NON Activated! That KMS K20 is from Nov. 11. 2012, means 9 month old and will may work with 9431 and KMS5! That said, it's clear there isn't a way to use an activator, KMS or whatsoever, for to activate Office 2013 on Build 9471 or later. I also wouldn't wonder if it not take a long time and the KMS activation for Server 2012 will change too!
Tested all current Emulators from MDL as Service installed and running as console app, KMSpico and the older MTK builds without success. Best message has been so far the 'Catastrophic Error' . Would guess Server 2012 R2 will feature KMS V6 likewise, but i highly doubt they will change it backwards for Server 2012 . Better question is will Server 2012 R2 still support SLIC 2.2....
which version of windows do have as your current version? is it w7 or w8? If you did not install w8 before, it seems that your cpu cannot handle 8 or 8.1
