Office 200 Pro (Score 1)

Years ago I had to buy MS Office Pro for Access. I bought the upgrade accidentally. I then saw the requirements for the upgrade, DOS and Wordperfect were list along with others. Well, when I went to install it, I got the upgrade error.. But they give you an option to point to a different drive to scan for licenses. When I pointed it back to the CD-Drive it ran the full install.
