Understanding MSI Error Code 1618

Overview

Section titled “Overview”

MSI Error Code 1618 is a common issue encountered during software installations or updates on Windows systems.

This error indicates that another MSI-based installation is already in progress, which blocks the current installation or update from proceeding. Although this error can occur while updating or operating the XDR Forensics Responder, it is not caused by the XDR Forensics Responder software itself.

Why Does This Error Occur?

Section titled “Why Does This Error Occur?”

The error code is related to the Microsoft Windows Installer service. It typically appears when:

  • Another installation is already running in the background (e.g., a Windows update or another MSI-based installer).
  • The Windows Installer service is locked by a pending installation or system process.

Since this issue originates from the Windows environment, resolving it involves managing the underlying MSI processes.

Steps to Resolve MSI Error Code 1618

Section titled “Steps to Resolve MSI Error Code 1618”
  1. Check for Running Installations
  • Manually verify if there are any ongoing installations:
  • Open Task Manager (Ctrl + Shift + Esc).
  • Look for any processes related to Windows Installer or other installation programs (e.g.,msiexec.exe).
  • End these processes if they are blocking the current installation.\
  1. Check for Pending Windows Updates

Sometimes, a pending or ongoing Windows update can cause this error. Follow these steps:

  • Go to Settings > Update & Security > Windows Update.
  • Check if there are any updates in progress or requiring a restart to complete.
  • Allow the updates to finish or reboot the machine to clear them.
  1. Restart the Windows Installer Service

Restarting the Windows Installer service can resolve locked or unresponsive installer issues:

  1. Open the Run dialog box (Win + R).
  2. Type services.msc and press Enter.
  3. Locate the Windows Installer service (msiserver).
  4. Right-click and select Restart.

4. Reboot the System

The simplest and most effective first step is to reboot the affected machine. Rebooting clears any pending installations or processes using the Windows Installer service.
