When I tried to upgrade, got a message saying ZoneAlarm Free Firewall (on Windows XP)couldn't tell which version I currently had (it was the one before the new one, from last December). Tried a full install of the latest version, which worked except gave me a completely blank ZoneAlarm interface screen so I had no idea what the settings were etc. Uninstalled, and tried again, and now I am in the position where installation fails everytime whether I use the official ZA website or another link. From the ZA download I get the message 'installation failed. The download file is not a Zone Alarm installer'. Tried Windows XP system restore, too & that made no difference. So I have no ZA and it won't let me downlad and install it. Please help.
Operating System:Windows XP Home Edition
Product Name:ZoneAlarm (Free)
