Zyzzyva is freely available to anyone and runs under Linux, Windows 98 or later, and Mac OS X 10.6 (Snow Leopard) or later on a 64-bit (Intel Core 2 Duo or later) processor.
The newest version of Zyzzyva, version 3.0.4, which includes OTCWL2014 (for NASPA members only) and other lexicons, is now available from the link below for Windows, Mac OS X and Linux machines.
There is a separate iOS app version of Zyzzyva, developed for the now dated iOS 6. Soon after our acquisition of Zyzzyva, we learned that its iOS app is not compatible with iOS 8. Work is proceeding on bringing the iOS app up-to-date, but we do not yet have a timeframe for completion.
Zyzzyva has been used at software self-lookup stations at many North American SCRABBLE tournaments, including BAT, Oregon TILE, the Dallas Open, the National SCRABBLE Championship, National School SCRABBLE Championship, the Canadian National SCRABBLE Championship and the World SCRABBLE Championship.

Please note that as of May 6 2015, Norton Antivirus has incorrectly flagged Zyzzyva as suspicious. As such, Norton users must train the antivirus software to ignore the folder where Zyzzyva lives (which is either C:\Program Files\NASPA Zyzzyva 3.0.4 or C:\Program Files (x86)\NASPA Zyzzyva 3.0.4, on Windows). Here is a good summary of how you to do so: http://antivirus.about.com/od/securitytips/ht/excludefilesfromnorton.htm
Here is a procedure used by one user to correct the Norton issue:

Next, before exiting Norton, exclude further activity against this program:
Zyzzyva should now be restored, and should not be quarantined by Norton in the future.
You may need to restore the program icon from the desktop shortcut at this point. To do so, follow these steps:
