Edit the file called EZ5VARS.BAT which is in the EASY5 installation directory (usually C:\MSC.Software\EASY5\2010.1.2 for EASY5 2010.1.2) per the instructions below.

NOTE: Make sure to make a back up of the file first in case the newly edited version doesn't work.

For the 32 bit version of the Intel compiler, add the following line to the ":SETUP_IF91" section:

call "C:\Program Files\Intel\Compiler\11.1\035\bin\ifortvars.bat" ia32

making sure that the path to the ifortvars.bat file is correct. The added line should go just before the last line in the section as shown in red below:

For the 64 bit version of the Intel compiler, add the following line to the ":SETUP_em64t_IF91" section:

call "C:\Program Files (x86)\Intel\Compiler\11.1\054\bin\ifortvars.bat" intel64

making sure that the path to the ifortvars.bat file is correct. The added line should go just before the last line in the section as shown in red below:
