Error message that you may receive when you try to view a Microsoft Management Console (MMC) snap-in: "Snap-in failed to initialize"

Symptoms

When you try to view a Microsoft Management Console (MMC) snap-in, you may receive the following error message:
Snap-in failed to initialize.
Name: Computer Management
CLSID:{58221C67-EA27-11CF-ADCF-00AA00Ai0033}
Note Examples of MMC snap-ins include the Services snap-in and the Event Viewer snap-in.

This problem occurs when the following conditions are true:
  • Microsoft Windows Embedded for Point of Service (WEPOS) is installed on the computer.
  • Microsoft SQL Server 2000 Desktop Engine Service Pack 3a (SP3a) has been upgraded to Microsoft SQL Server 2000 Desktop Engine SP4.

Cause

This problem occurs because the Microsoft Windows Installer package for SQL Server 2000 Desktop Engine SP4 that is included in Microsoft Point of Sale (POS) 1.0 incorrectly deletes the %Windir%\System32\Atl.dll file. Additionally, because Windows File Protection is not installed on computers that have WEPOS installed, Windows File Protection cannot prevent Windows Installer from deleting this file.

Resolution

To resolve this problem, you must replace the missing Atl.dll file. To restore the Computer Management MMC to full functionality, follow these steps:
  1. Click Start, and then click Run, type the following command, and then click OK:
    Copy C:\Windows\winsxs\x86_microsoft.tools.visualcplusplus.runtime-libraries_6595b64144ccf1df_6.0.0.0_x-ww_ff9986d7\atl.dll %windir%\system32\

Status

Microsoft has confirmed that this is a bug in the Microsoft Windows Installer package for SQL Server 2000 Desktop Engine SP4.

More Information

Steps to reproduce the problem

  1. Upgrade the computer to SQL Server 2000 Desktop Engine SP4 from POS 1.0.

    Name: Computer Management CLSID:{58221C67-EA27-11CF-ADCF-00AA00Ai0033}
