How can I transfer my Microsoft Office Install to another Mac?
You can try to move the main folders to an external drive:


/Applications/Microsoft Office 2011
/Applications/Microsoft Messenger.app
/Applications/Microsoft Communicator.app
/Library/Application Support/Microsoft
/Users/username/Library/Preferences/Microsoft
/username/Documents/Microsoft-Userdata


Copy these Folders to the same path on your new system.
