Install .Net 3.5 feature and MPI's



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

On a Windows computer, where Lumerical’s product installation is not able 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

Install MPICH2

Install Intel MPI

Install the Product

  • Finally, if you need to install the Product Design Software, run the Installation file, [Product]_data.msi, from the installation folder.

These should install everything required to run the Product.
