I have Windows XP SP3 and the newest version of ZA Internet Security Suite. Every time I update the anti-virus updates the anti-virus updates but then I get System:Error:Unable to install. Been going on for 2 or 3 months and I have been waiting for a new total update hoping it would fix this but so far no new version and I still get the error and I can find no info on how to fix this. What gives?
