SYMPTOMS

When you run the Office Setup program, you may receive the following error message:
Error 1327. Invalid Drive: C:\

Installation ended prematurely because of an error.
When you click OK, Office Setup quits.

NOTE: This error occurs during the installation of the System Files Update.

CAUSE

This problem can occur if you use the Disk Administrator utility that is included in Microsoft Windows NT 4.0 to change the drive letter of the hard disk where the operating system is installed; for example, the C drive.

The problem occurs because the Office Setup program uses registry keys to determine the locations of certain folders that are required to install Office. If the drive letter of the hard disk that contains the operating system is changed, the registry keys refer to nonexistent folders, and Setup fails.

RESOLUTION

To resolve this problem, use the Windows NT Disk Administrator utility to restore the drive letter of the hard disk to its original value. To do this, follow these steps:
  1. Click Start, point to Programs, point to Administrative Tools, and then click Disk Administrator.
  2. Right-click the drive whose letter you want to change. On the shortcut menu, click Assign Drive Letter.
  3. Select the correct drive letter from the list, and then click OK.
If you are prompted to quit the Disk Administrator or to restart your computer, do so. After the computer restarts, run Office XP Setup again.

MORE INFORMATION

If you use the Disk Administrator utility in Windows NT to change the drive letter of the hard disk where the operating system is installed, you receive the following message:
Changing the drive letter for the windows directory may produce unexpected results. Are you sure you want to continue?
