SYMPTOMS
When you run Office Setup, you may receive the following error message immediately after you click Install Now or Upgrade Now:

Installation ended prematurely because of an error.

When you click OK, Setup ends.



CAUSE
This error may appear if all the following are true:
 * You are using Microsoft Windows NT 4.0. -and-


 * You are running Office Setup from a CD-ROM drive. -and-


 * You are using one of the security templates available with the Microsoft Security Configuration Manager. -and-


 * You have the Restrict CD-ROM access to locally logged on user only security option turned on.

This is because the Windows Installer runs as Local System when it is read off the CD-ROM drive. The problem is that Local System is denied access to the CD-ROM drive when this security policy is set.

NOTE: This error message also may appear if you do not have the Restrict CD-ROM access to locally logged on user only security option turned on but the AllocateCDRoms value under the following registry key is set to 1:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon



WORKAROUND
To work around this problem, do either of the following:

Method 1: Run Setup from a Network Server
If you are in a networked environment and you have access to an administrative installation of Office 2000, run Setup from this location instead of your CD-ROM drive. The security settings mentioned in the "Cause" section of this article do not affect running Setup from a network server.

Method 2: Turn Off the "Restrict CD-ROM Access to Locally Logged on User Only" Security Option
If you turn off the Restrict CD-ROM access to locally logged on user only security option, you can run Setup from your CD-ROM drive. Please see the documentation on the Microsoft Security Configuration Manager for more information about modifying this setting.

NOTE: You may have to restart after you turn off the Restrict CD-ROM access to locally logged on user only security option before you can run Setup from your CD-ROM drive.

MORE INFORMATION
One way to verify whether you are experiencing this problem is to create a verbose log file and search for the following text:

MSI (s) (AF:C0): Note: 1: 2318 2: H:\data1.msi

MSI (s) (AF:C0): MainEngineThread is returning 1603

MSI (c) (BB:93): Back from server. Return value: 1603

Action ended 19:53:03: ExecuteAction. Return value 3.

MSI (c) (BB:93): Doing action: FatalError

To create a verbose log file, do the following:  Click Start, and then click Run. In the Open box, type the following and then click OK:

\setup.exe /L*v c:\Officelog.txt

The verbose log file Officelog.txt is created on the root of your drive C.
