Your user privileges do not allow Fireworks to update your registry

I installed Fireworks in my Lab where 200 PC’s were available and are connected with server. When I installed this software to my PC at home, it worked properly. When I used this software in my lab, I received the given error. I installed this software at client machine by logging-in through administrator account. Then why  did I receive this error when admin have complete rights?
