Intel® MPI Library Developer Guide for Windows* OS
If you have a previous version of the Intel® MPI Library for Windows* OS installed, you do not need to uninstall it before installing a newer version.
To install Intel MPI Library, double-click on the distribution file w_mpi_p_<version>.<package_num>.exe (complete product), and w_mpi-rt_p_<version>.<package_num>.exe (RTO component only).
You will be asked to choose a directory in which the contents of the self-extracting installation file will be placed before the actual installation begins. After installation, the files will still be located in this directory. By default, C:\Program Files (x86)\Intel\Download is used on machines with Intel® 64 architecture.
Follow the prompts outlined by the installation wizard to complete the installation.
You need the domain administrator rights when you install the Intel® MPI Library on Windows* OS. Otherwise, you cannot proceed with the Active Directory* setup on Windows* OS. See the Intel® MPI Library Developer Reference for more Active Directory* setup information.
