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.
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
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.

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
Action start 19:53:03: FatalError.
To create a verbose log file, do the following:
  1. Click Start, and then click Run.
  2. In the Open box, type the following and then click OK:
    <CD-ROM drive>\setup.exe /L*v c:\Officelog.txt
    The verbose log file Officelog.txt is created on the root of your drive C.
