R3load -testconnect falied Maxdb |IDES EHP7 installation

Hi Experts,

I'm installing IDES EHp7 with maxdb and getting error at phase ABAP import.

An error occurred while processing option SAP Business Suite 7i 2013 Support Release 2 > EHP7 for SAP ERP 6.0 ABAP Support Release 2 > MaxDB > SAP Systems > Application Server ABAP > Standard System > Standard System( Last error reported by the step: Process call 'F:\usr\sap\ARH\SYS\exe\uc\NTAMD64\R3load.exe -testconnect' exits with error code 2. For details see log file(s) R3load.exe.log.).

Maxdb version is MaxDB_7.9 and kernel is 750 patch 100.

Appreciate any help.

Regards,
Dipesh G.
