Hello.
As far as possible try not to install ZoneAlarm in Safe Mode, my work in the ZoneLabs forum tells me that that usually gives rise to a lot more problems.
it keeps telling me there;s a driver incapability even though i;m downloading
Zonealarm for vista
When do you get this error message? During the installation? It would help if you can provide a clearer explaination, and a screenshot would be even better.
