Earlier this year I bought a new laptop (with Windows Vista). I bought and installed Zone Alarm Extreme Security; the purchase allowed me to install it on two computers, but for most of this year I've only had it on the one. My husband recently needed to renew his antivirus protection, so we decided to install ZAES on his computer (which has Windows XP Home) instead, using my license number. Everything went fine, and ZAES is working fine on his computer, and even the expiration date of the product corresponds with mine. But under product info it says "This copy of Zone Alarm Extreme Security has not been registered." Do I need to be worried about this? Is this normal in cases of two computers on one license number? Is there anything I need to do to ensure it is properly registered on his computer?
