I was prompted to upgrade Zone Alarm so that it would be compatible with Windows Vista. After downloading the upgrade and restarting my computer, Windows Boot Manager states that Windows failed to start, and that it may be a result of a recent hardware or software change. To fix the problem I am asked to insert the Windows Installation disc and restart the computer. I inserted the upgrade disc from XP to Vista and restarted my computer, but I am prompted with the same warning. Does any one have any idea what I can do? I do not know the version of Zone Alarm that I have.

Operating System:Windows Vista Home Basic
Software Version:
Product Name:ZoneAlarm Antivirus
