Reporting Services Extension install validation error ?

hi, we are on AX 2012 R2 and CU7

On the Sql side we are on Sql server 2008 R2 SP2. As part of installing Reporting Services Extensions, the validation fails with this error:

If you are installing on MS Sql Server 2008 R2, CU3 or higher is required

as per this article - http://technet.microsoft.com/en-us/library/hh285826.aspx i went ahead and installed the latest CU 13 for Sql Server 2008 R2. But still the validation error is not going away.

Any help is highly appreciated.

Thanks,

San
