I want to Parallel compute a file in windows 64,the computer is installed :
mpich2-1.4.1p1-win-ia32.msi
SU2-3.0.000-64-bit-Parallel.exe
python 2.7
numpy and scipy
When computing a file,I enter the "python parallel_computation.py -f
turb_ONERAM6.cfg -p 2 " in cmd.exe and face the error:

the command:mpiexec -np 2 D:\Program Files\SU2\SU2_DDC config_DDC.cfg
the location: D:\
launch failed:CreateProcess<D:\Program Files\SU2\SU2_DDC config_DDC.cfg>on 'owner-PC' failed,error 2 -system can't the file
launch failed:CreateProcess<D:\Program Files\SU2\SU2_DDC config_DDC.cfg>on 'owner-PC' failed,error 2 -system can't the file
(.su2 and .cfg are located at D disk,the softare are located at D:\Program Files\SU2 and make environment variable as 'path' )

I want to the reason.Thanks

Two issues:

- MPICH2 has discontinued Windows support entirely and hence SU^2 no longer supports it on the Windows platform. The executables are built with Microsoft's MPI implementation which can be downloaded for free as part of the "HPC pack". Please refer to the SU^2 Windows installation documentation for a link and details.

- (Just an FYI) It looks like you're trying to run the 32-bit version of MPICH2 on a 64-bit Windows system.

thank your advice,I reinstall the MS MPI and SU2 to C:,and it seem run,but I face the issue,the Dos is showing:
D:\>parallel_computation.py -f inv_NACA0012.cfg -p 2
the command: mpiexec -np 2 C:\SU2\SU2_DDC config_DDC.cfg
the location: D:\
