Although the file you are trying to download and open is a Windows 95 self extracting zip archive, a Mac user should still be able to open it using a program such as ZipIt or Stuffit Deluxe. Simply try to open the file as if it were a normal zip archive. ZipIt and Stuffit Deluxe are smart enough to ignore the Windows 95 self-extracting code and concentrate on the data in the archive.
