Binaries in VB?

We have a visual basic program running our meal service (college). It was written some years ago, and the original programmer is gone, but the program itself runs off our server. We recently tried to move this program, only to find that it points to itself (hardcoded), rather than assuming the default directory. When trying to open it in modern VB (4+) it states that it cannot open the binary file. I’m pulling my hair out, any suggestions?
