Dear All, I would like to install the MPICH3.0.3 on Windows, but I am having problems with it. Although the manual tells that it can be compiled as: Download mpich-x.y.z.tar.gz and unzip it. Bring up a Visual Studio Command prompt with the compiler environment variables set. Run winconfigure.wsf. If you don't have a Fortran compiler add the --remove-fortran option to winconfigure to remove all the Fortran projects and dependencies. Execute winconfigure.wsf /? to see all available options. it is impossible to do so, as winconfigure.wsf does not seem to be correct (Line 280; there is no src/common directory; the script always fails to run). I used Visual Studio 2010 Command Prompt (winconfigure.wsf --remove-fortran). Can anybody help me how to compile it? Best regards, Laszlo
