Notes:

1. The Intel Fortran installation folder naming structure has changed many times over the years. 

2. The IFORT_COMPILERxx value depends on the Intel Fortran version, or update + build numbers.

3. One should not attempt to manually fix these environment variables. Instead they should either re-install that Intel Fortran version, or use the FortranMedic to create these variables if needed and set them to the correct value for that machine.

4. Background

When PSCAD uses the Intel® Fortran Compiler and Microsoft® Visual Studio software combination to build projects, the variables for these products are normally added to the enviornment during the installation of these products. However, sometimes the variables do not actually become added during the installation for some reason, and consequently, the projects cannot be compiled.
