MPICH2 unable to exectue mpiexec in Windows 7

After installing MPICH2 in Windows 7, I tried mpiexec -n 2 cpi in \MPICH2\examples folder. But I got error message.

Fatal protocol error: check version between Mpiexec.exe, Msmpi.dll, and Smpd.exe.

1) In addition you can check the folders using

where mpiexec.exe
where smpd.exe
where msmpi.dll

2) Also you can uninstall one of your MPI instalation (or reinstall it - sometime it works).

3) Another solution is to link statically.

You may have another mpiexec.exe in one of the folders of the system path. Try specifying full path in front, such as: "C:\Program Files\MPICH2\bin\mpiexec.exe".
