If you can locate the files on the old hard drive you can move the files over, but you also have to go into the registery and export the registry keys for office and import them on your new computer.

To access your register go to start > run > type "regedit"

On your old hard drive it won't make a big difference if you mess something up, but when you import the registry to you new computer make sure you dont delete or change anything already there, it could mess up existing programs.
