I have using Win XP on my home computer and have used "TrendMicro Internet Security" as a firewall and antivirus for years. I recently resubscribed for another year, downloaded it succesfully and I am quite happy with it. Not long ago I bought a new HP laptop to take with me as i travel. It came with VISTA as an OS, no choice there. TrendMicro allows you to use their Internert Security 2007 on three machines, so I downloaded it onto the Laptop. However, when I try to install it, I get the message, "A FATAL ERROR IN YOUR WINDOWS OS HAS STOPPED THE SETUP PROGRAM. PLEASE RESTART YOUR COMPUTER BEFORE TRYING AGAIN." I have spent a long timeon the phone with TrendMicro but have no success as yet. Anybody have any ideas as to fixing this problem?? :-?
