Melissa:
Besides cost, the only difference between Upgrade versus Full Retail
versions are in the install routine. The upgrade requires a qualifying
product (such as Office 97). During installation, the upgrade will search
your hard drive for qualifying product. If a qualifying product is
installed, the new version will install without interruption. If a
qualifying product isn't installed, the installation routine will prompt you
to put the CD of the qualifying product into the CD drive. After the
installation routine has verified that the CD is a qualifying product,
installation will continue.
Note: If you lose/have lost the Office 97 CDs and your current computer
dies, you WILL NOT be able to install the Upgrade version of Office on a
replacement computer, as you will not have the qualifying CD.
