Trying to upgrade Windows Server from 2008 R2 to 2012. On compatibility check throwing an error

Active Directory on this domain controller does not contain Windows Server 2012
ADPREP /FORESTPREP updates. See http://go.microsoft.com/fwlink/?LinkId=113955.  

As per the suggested above link did what required; but still throwing same error.

Any helps?

@Nev, I had the same error. The Microsoft link suggest to use the Windows 2008R2 disc, however the updates are on the 2012 disc. For me the solution was to perform the Microsoft solution with the Windows 2012 disc and reboot. The same goes for the ADPREP /DOMAINPREP updates.
