JSI Tip 9274. When you attempt to install the Windows Installer 3.0 redistributable package, the event log records error 7023, Overlapped I/O operation is in progress?

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/YYYYTime: HH:MM:SSUser: N/A Computer: 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 offfor /f "Tokens=4" %%v in ('filever /A /D %SystemRoot%System32msi.dll') do ( set cv=%%v)if "%cv%" LSS "3.0.3790.2538" "\ServerShareWindowsInstaller-KB884016-v2-x86.exe"endlocal

NOTE: FileVer.exe is from your operating system's Support Tools on the CD-ROM.
