When you try to install one of the components in Microsoft Works Suite, you may receive the following error message
Error: 1327 Invalid Drive:drive:\
where drive is the drive letter of the CD-ROM drive.
This behavior can occur if the CD-ROM drive letter has changed since you originally installed Works Suite. For example, the letter for your CD-ROM drive may change after you install a second hard disk or a ZIP drive.
Additionally, this behavior can occur if Microsoft Works has been previously installed and removed from your computer.
To resolve this issue, delete the Works Suite registry keys from the Microsoft Windows Registry.
