Windows Installer (MSIServer) Service Defaults in Windows XP

Adds, modifies, and removes applications provided as a Windows Installer (*.msi) package. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Settings

Startup type:Manual
Display name:Windows Installer

Error control:normal
Object:LocalSystem
Path:%SystemRoot%\system32\msiexec.exe /V

Default Behavior

Windows Installer is a Win32 service. In Windows XP it won't start until the current user starts it. When the Windows Installer service is started, it is running as LocalSystem in a shared process of msiexec.exe. Other services and drivers are allowed to run in the same process. If the Windows Installer fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the MSIServer service has failed to start.

Dependencies

Windows Installer depends on the Remote Procedure Call (RPC) service.

Restore Default Startup Configuration for Windows Installer

1. Select your Windows XP edition and service pack, and then click Download.

2. Save the WinXP_MSIServer_Service_Startup.cmd file to a local storage device.

3. Run the saved file.

4. Restart the computer.

The MSIServer service is using the msiexec.exe file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows XP installation media.
