Below is a link to a special preview version of the upcoming ZoneAlarm (free version) with 64-bit compatibility. This is for advanced technical testers only, and it will only install if you are running a 64-bit computing system with a full and current version of Windows XP Pro 64. If you are running the 32-bit Windows XP on a 64-bit machine, this preview version will not install. Do not attempt to run this version on any platform other than Windows XP Pro 64.
As this is an early preview version of the program, it may cause instability of your system or other technical issues. Prior to installing this ZoneAlarm preview, back-up all of your files and make sure you have copies of all other programs currently installed on your 64-bit PC in case you need to restore your system.
We do NOT suggest using Beta software unless you are familiar with editing the registry, manually removing the product, and so on. Remember that there is NO technical support for the Beta versions.
