How to Fix “Another program is being installed” Installer Error on Windows 10

Windows 10 does not support the concurrent installation of multiple apps. You can install one app after another but you cannot run multiple installers at the same time.

This is because when an app is installed, it creates directories and writes to the registry. The process cannot be interrupted or run parallel to another similar process. The chances of error would be far too great.

How to fix Another program is being installed

Regardless of the cause for the error, you can run through the following fixes and resolve it.

1. Wait for the installation to complete

Many apps will show an on-screen progress bar as they go through the various steps of installation however, not all of them do. Some apps, especially those that install additional libraries may do so silently in the background. If you see the Another program is being installed… Installer error, wait at least fifteen minutes for the installation to complete, and then try installing a second app. 

2. Manually quit the installation

If the app’s installation hasn’t finished after waiting for a reasonable amount of time, you can manually quit it. You should know that this may result in the app not installing correctly or at all.

  1. Right-click the taskbar and select Task Manager from the context menu.
  2. Go to the Processes tab. 
  3. Look for the installer/EXE/MSI process and select it.
  4. Click the End task button at the bottom right.

3. Eject installation media

Try removing any installation media that you’ve connected to the system e.g., a DVD, CD, or USB drive. Doing so will likely interrupt the installation process but it will allow you to install the second app.

4. Restart the system

If all else fails, you can restart the system. When the system restarts, it will quit all on-going processes and they will not run again when you boot back to the desktop.

5. Run a virus scan

The app that you’re trying to install may be malicious and one reason why its installation will not complete, or why it is blocking other apps from installing. Run a virus scan with Windows Defender.

  1. Open Windows Defender.
  2. Go to the Virus and threat protection tab.
  3. Click Scan Options.
  4. Click Scan Now.
  5. Scan the entire system and remove any infections that are found.

Note: It’s also a good idea to scan your system with the free version of MalwareBytes.

Conclusion

If you have an app that never finishes installing, it may be corrupted. You can try downloading it again and running the installer but there is a good chance there is a problem with the installer itself. In this case, there isn’t much you can. Find an alternative to the app and uninstall any component of the app that may have been installed.
