Try to set the ifort environment variables with "ifortvars ia32". You should find ifortvars.bat somewhere in the bin directory of your Inter/Compiler/Fortran ... This way you make sure you have got everything, the PATH, the LIB and the INCLUDE.
Alternatively, you can also directly open an Inter Fortran DOS command windows:
Programs => Intel Software Development Tools => Intel Fortran Compiler => Fortran Build Environment ...
Hope this helps.
