yes the program and its supporting programs are installed (i would show you an 'ls' output but there are hundreds of them). Code: [FILE] Bin_Path=c:\G03W Input_Path=c:\G03W Output_Path=c:\G03W ScratchDir_Path=c:\G03W\Scratch This was created by the gaussian program. This was my first approach to fixing the problem, but no matter what type of paths i use i get the same error. I have checked gaussview for any option which let me manually find the folder buy it must be in the back-end somewhere.
