To back up your licenses

On the Tools menu, click License Management.
Click the Browse button.
Select the location for the backup copies of your licenses, and then click OK.
It is recommended that you back up your licenses to a floppy disk.
In the License Management dialog box, click Backup Now.
Note You should back up your licenses to a floppy disk periodically. If you reinstall or upgrade the operating system, your licenses could be lost. You can use the back up disks that you create to transfer licenses from an old computer to a new one, or to transfer licenses from a work computer to a home computer.
