Before doing my Tiger clean install, I cloned my Powerbook harddrive to an external firewire drive using Super Duper!. I've never done a backup and restore before, so I have no idea how to get applications installed from a backup. Thing is, I split the cost of a 3-license Academic Version of Office 2004 with my former roommate, and he took the installation CDs. I just want to get Office back on my tiger system, but something tells me I can't just drag and drop the folder, since installs usually make system wide changes(Application support folders, Preference files, etc....). Any tips on how to proceed, or do I absolutely need the original install CD's?
