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.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
