Understanding and Fixing Sage Error 1618

Sage Error 1618 is a common issue that users might encounter while trying to install or update Sage software. This error typically indicates that another installation is currently in progress, and the system cannot initiate a new one. It can be frustrating as it halts the installation process, preventing you from accessing the latest features or using the software altogether.

Causes of Sage Error 1618

This error can stem from a few different reasons:

  • Reason #1: The most straightforward cause is that there is genuinely another installation process running on your computer. This could be an update for another program, a new software being set up, or a previous Sage installation that didn’t conclude properly.

  • Reason #2: Sometimes, the Microsoft Installer (MSI) service encounters glitches. Since Sage and many other applications rely on this service for installation, any issues here can lead to Error 1618.

  • Reason #3: In rare cases, the error may be triggered by registry problems or conflicts within the Windows operating system itself, which mislead the system into thinking an installation is running when it’s not.

Solutions for Sage Error 1618

Solution #1: Check for Running Installations

  1. Press Ctrl + Alt + Delete and choose Task Manager.
  2. Go to the Processes tab and look for any processes named "Installer," "Setup," or similar.
  3. If you find such a process, right-click it and select End Process.
  4. Try running the Sage installation again.

Solution #2: Restart the Microsoft Installer Service

  1. Press the Windows key + R to open the Run dialog.
  2. Type services.msc and press Enter.
  3. Scroll down to find the Windows Installer service.
  4. Right-click on it and choose Restart. If Restart is greyed out, select Start.
  5. Once the service has restarted, attempt to install Sage again.

Solution #3: Use the Microsoft Program Install and Uninstall Troubleshooter

  1. Download the troubleshooter from the official Microsoft website.
  2. Run the tool and follow the on-screen instructions to detect and fix issues with the installation services.
  3. Try to install your Sage software once the troubleshooter has completed its task.

Solution #4: Clean Boot Your Computer

  1. Press the Windows key + R, type msconfig, and press Enter.
  2. In the System Configuration Utility, go to the Services tab.
  3. Check the box to Hide all Microsoft services, then click Disable all to turn off third-party services.
  4. Switch to the Startup tab and click Open Task Manager.
  5. In Task Manager, disable all startup items.
  6. Restart your computer and attempt the Sage installation again.


How do I know if another installation is actually in progress?

Check your system tray (bottom-right corner by the clock) for installation prompts. Also, look at your task manager for any running installation processes or setups.

What if the solutions don’t work?

Try running the installation as an administrator by right-clicking the setup file and selecting Run as administrator. This can sometimes bypass the issue.

Can Sage Error 1618 affect updates as well?

Yes, Error 1618 can occur not only during the installation of Sage software but also when attempting to run updates for an already installed application.

Is restarting the computer a viable solution?

While not a direct solution, restarting your computer can sometimes resolve underlying issues causing Error 1618 by resetting the state of the Windows Installer Service and terminating any invisible installation processes.

By following these solutions, you should be able to resolve Sage Error 1618 and continue with your software installation or update. If the error persists, it might indicate a deeper issue within your system, which may require more advanced troubleshooting steps.
