Per the DP 7.x support matrix
http://support.openview.hp.com/selfsolve/document/KM1357659 pg 8-9
this is an unsupported configuration, running on Windows 2012
At the current time, only SQL Server 2012 is supported to run on Windows 2012 (NOT R2!!) with DP 7
I checked the support matrix for DP 8, and this configuration is supported. I woulkd caution you about upgrading to DP 8, it still has its issues with the new IDB among other things. You may want to submit an enhancement request to have your configuration supported with DP 7.03
