[lammps-users] I cannot install

I have tried to install lammps but i have run into this error that says can not find mpich2mpi.dll. The real issue though is that i have installed mpich2 AND found this file myself using the search function on my windows xp x64. I would really like top use this program and assistance would be very nice.

Thank you in advance

Did you download a Windows executable for LAMMPS from the
download page? Or build it yourself from source code
in which case you should have some kind of Makefile where you
can specifiy where libraries like MPI are on your box.
