I purchased microsoft office in May by dowloading from site. I didn't get the disk; now I need to install to my laptop. Can I just purchase the disk, or must I buy the whole thing again?

You can uninstall MS Office from the computer first.

Then download MS Office to the laptop and activate it using the key from the uninstalled MS Office.

Another option is to borrow an MS Office DVD and then use your key to activate it after installation.

All that Microsoft requires is that MS Office is running only on one computer (single licence version).
