We are happy to announce that Microsoft Dynamics AX 2012 R2 CU7 is now supported with Windows Server 2012 R2 and SharePoint 2013 SP1. Please refer to the Microsoft Dynamics AX 2012 System Requirement document for more information.
Note You should avoid creating your own slipstream versions of SharePoint 2013 by putting SP1 in the updates folder, because of a change in the package layout that was introduced with the March 2013 product update. The March update was a pre-req for install
Enterprise Portal on Ax 2012 R2. Download SharePoint 2013 WITH SP1 build instead. Please see
