I've used the same serial number to install office 08 on both my desktop and laptop. Since their on the same LAN office 08 prompts me saying that when one is open on one of the computers, I cant open it on the other. So now i've got a new serial number to put on the second machine but anytime I go to reinstall office, it will not prompt me for the new serial number. It will just use the same old one. I've uninstalled office completely and it just wont work. Any advice?
