HEED self-installs as a stand-alone program on Windows PCs. HEED can also be run in Spanish (see the HEED en Español icon).

This newest Build 22a is similar to the prior Build 22 except that it resolves a problem some users had with graphics. It now calculates window shading from overhangs and fins, but not yet from trees or neighbors. If you install this new version in an existing HEED folder, it will preserve your prior design data. Other wise you can start fresh by installing it in a new folder that you might call HEED-22a:

NOTE: If you are having difficulty installing or running HEED, be sure to follow the default procedure which installs HEED at the top level (C:\HEED), and do not use folder names longer that 8 characters. If you are running behind a firewall or on a network, stop and see your systems administrator for permission to install it. If you get an OpenGL warning or strange graphics behavior be sure you have installed the latest version of your graphics driver and that you have the current Windows Service Pack installed. If you are a Vista or Windows 7 user who is having difficulty, you might first designate yourself as Systems Administrator (go to Settings, Control Panel, Users). Vista installation problems might be solved if you temporarily lower their level of security. In both cases however, once installed you should return to your original configuration. Advanced Vista users might consult Microsoft's User Account Control Step-by-Step Guide.

To install HEED on Mac OS X, drag the HEED icon from the installation folder to your Applications folder.

HEED runs on Mac OS X 10.7 (Lion) and Mac OS X 10.6 (Snow Leopard). (Choose About This Mac from the Apple menu to see your version information.)
