MMSIM12.11 error while running simulation

[jagrut_am]

I have installed mmsim 12.11 along with IC615 and i get the following error while simulating a design

ERROR (ADE-3036): Errors encountered during simulation. The simulator run log has not been generated.
Possible cause could be an invalid command line option for the version of the simulator
you are running. Choose Setup->Environment and verify that the command line options
specified in the userCmdLineOption field are supported for the simulator.
Alternatively, run the simulator standalone using the runSimulation file in the netlist
directory to know the exact cause of the error.

I have changed my enviroment settings to use 64 bit binaries but still getting the same error.
Please help me figure out this problem.

Thank you.
