We are celebrating the 10th anniversary of Lucid's initial release by providing “Lucid v3.3” free*.

Lucid v3.3, which was released in 2006, operates on Windows98/ME/NT/2000/XP/2003/Vista, OSX, Linux, and Solaris and is capable of producing keys for deployment on CD or the Internet.

Lucid v3.3 is compatible with the latest Lucid v3.6 builder, so that any keys developed using Lucid v3.3 can be easily imported to Lucid v3.6.

Updated version now available (v3.3.6 20161212 FREE)
Removes applet deployment support due to issues with the JRE and Java Plugin in Chrome and other browsers.
