Install .Net 3.5 feature and MPI



Turn on .Net 3.5 feature and install MPI on Windows.

For instances on a Windows computer, where the Product Installation package is unable to install DotNet 3.5 and Microsoft MPI automatically, or you get an installation error.

A work around is to manually enable and install these components and the software.


On Windows 8 and 10 machines, .Net 3.5 is going to be installed as part of Windows update. If you are logged into your domain or active directory, please check with your IT department.**

  • Install .Net 3.5 by turning this feature ON in your computer:

    Control Panel > Programs > Programs and Features > Turn windows feature on and off,

  • install Microsoft MPI by opening the folder MSMpi from the Installation folder and running the file, MSMpiSetup.exe

  • install MPICH2 by opening the folder mpich2_x64 from the Installation folder and running the file, mpich2redist_x64.msi

  • Finally, run the product Installation file, [Product]_data.msi, from the installation folder.

    These should install all the necessary software to run the Product.
