I cannot for the life of me compile a f77 program with this software. I always get the error: FTN77 must be on the PATH. I'm pretty sure I figured out how to add stuff to my PATH, but I looked in the program folder and I don't see anything with "FTN77" in the name, so I have no idea what to add to the path. According to the website, this program should compile ftn77. Any ideas? I really don't want to download another compiler (especially since I tried downloading g77 and can't even get things unzipped).
