When you attempt to install the Windows Installer 3.0 redistributable package, the event log records an error that is similar to:

Event Type: Error                               Event Source: Service Control Manager                               Event Category: None                               Event ID: 7023                               Date: MM/DD/YYYY                              Time: HH:MM:SS                              User: N/A                               Computer: <ComputerName>                              Description: The Windows Installer service terminated with the following error: Overlapped I/O operation is in progress.
This behavior will occur if the computer has a later version of Windows Installer installed, because the Windows Installer 3.0 redistributable package incorrectly updates the registry when a later version is already installed.

To recover from the registry corruption:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

msiexec.exe /regserver

To avoid this situation, use a script to install the Windows Installer 3.0 redistributable package, similar to:

@echo off                              for /f "Tokens=4" %%v in ('filever /A /D %SystemRoot%\System32\msi.dll') do (                               set cv=%%v                              )                              if "%cv%" LSS "3.0.3790.2538" "\\Server\Share\WindowsInstaller-KB884016-v2-x86.exe"                              endlocal
NOTE: FileVer.exe is from your operating system's Support Tools on the CD-ROM.
