HELIOS has been developed using cross-platform C++ user interface (UI) software. HELIOS also utilizes the OpenGL graphics application framework. The use of cross-platform UI software and OpenGL allow HELIOS to be supported for MS Windows, Unix, and Mac platforms.

HELIOS is currently supported for:

• MS Windows (NT, 98/2000, XP)
• Linux
• Mac OSX.

Windows versions of this software can also be run on non-Windows platforms using emulators such as Virtual PC (Mac OXS) or VMWare (Unix).
