I use a time machine backup to build MAC’s for our employees, saves me time on install and configurations, however our MAC users use office 2008 and require a unique key from our licensed copy. to re enter the office serial I just run the following two commands in terminal :

rm "/Applications/Microsoft Office 2008/Office/OfficePID.plist"
rm "~/Library/Preferences/Microsoft/Office 2008/Microsoft Office 2008 Settings.plist"


and re launch office.

echo "umask 002" >> /etc/launchd-user.conf.

reboot
