the compiler commander ifort could not be found

Hello,

I have Parallel Studio XE 2015, Microsoft Visual Basic 2010 Express, Microsoft Visual Studio 2010, & Microsoft Visual Studio Professional 2013 installed.  I have been trying to compile fortran using the Windows SDK 7.1 Command Prompt and it keeps giving me the error that the compiler commander ifort could not be found.  I really don't understand what the issue could be, if it is something to do with the software or just the way I have it set up?  I can easily compile C code so I know that works.

Thanks,
