Error During ECC6 EHP7 IDES INSTALLTION

          Hi Experts,

I am getting below error during the installation of SAP IDES ECC6 EHP7

       An error occurred while processing option SAP Business Suite 7i 2013 Support Release 1 > EHP7 for SAP ERP 6.0 ABAP Support Release 1 > MS SQL Server > SAP Systems > Application Server ABAP > Standard System > Standard System( Last error reported by the step: Creating a license signature failed: ===...could not load SSF library D:\usr\sap\\D00\exe\sapcrypto.dll .). You can now:

• Choose Retry
  to repeat the current step.
• Choose Log Files
  to get more information about the error.
• Stop the option and continue later.

Log files are written to C:\Program Files/sapinst_instdir/BS2013/BS2013SR1/ERP607SR1/MSS/INSTALL/STD/ABAP.    

Please guide me.

-Regards
