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??   :-?You may need to update that package...according to TrendMicro it is Vista READY but the version you have even though it is 2007 might not be complete...

Check their site for a Vista patch.reminds me of that new Mac commercial for Vista.
But yea, my advice is also to get the latest version and try again.Actually it's a Mac commercial for Mac....
