    Helic 1.0 is the latest and probably final version of HELIC, since Don Arnush passed away in 2003.  The following .EXE file is a self-extracting ZIP file.  First create a new folder, e.g.  "Helic", and extract to it.  Included are Word and PDF copies of the Instructions and the Equations (which are also in the Help section  of the program).   With all the files in the same folder, the program is started by double-clicking on Helic10.exe.   By clicking Start.exe, you can access the DOC and PDF files, and also install the program to another directory.  If all the files are written to a CD, the opening menu for installation will appear automatically.
