I need your help as an error message often occurred .It was 'LENOVO-PC error = LENOVO-PC: MPICH2 not installed or unable to query the host'

I had closed the firewall according to the instruction.My version of MPICH2 was 'mpich2-1.4.1p1-win-x86-64' and my computer is operating on Win7-64 system.

I really need a solution to the problem.

Thank you very much.
