Cause of Windows Installer Package Errors

When you get an alert or warning message telling you there's a problem with your Windows installer package, this usually means a program isn’t running properly. This can be caused by programs or apps conflicting with one another, a virus or malware infection, a lack of sufficient system memory to power all of the running apps, or a graphics driver error.

How to Fix a Problem With Windows Installer Package

Here are some of the best things to do when your Windows computer tells you there’s a problem with your Windows Installer package.

  1. Restart your computer. Restarting Windows can fix a variety of problems including Windows Installer package errors.

  2. Update Windows. Performing a Windows update will scan your device during the update process and fix a number of conflicts that may be present. The update process will also update the operating system and drivers which could repair the cause of the Windows Installer package error.

  3. Update your Windows apps. If you haven’t updated your apps, now is the time. In addition to adding new features, app updates can also improve security and squash any system conflict bugs.

  4. Run a Windows Troubleshooter. Go to Settings > Update & Security and run the Program Compatibility Troubleshooter and Windows Store Apps Troubleshooter. Both will scan and provide solutions for any app problems that are making this error message occur.

  5. Repair the app. On Windows 8 and 10, right-click an app’s icon or tile, then select More > App settings > Repair. This will scan just the app and fix any errors in its coding.

    On Windows 7, you’ll need to do this from Control Panel > Uninstall a program, right-click an app name, then select Change > Repair.

    The Repair option may not appear for all apps.

  6. Reset the app. Resetting an app is a way of refreshing it without having to delete it completely and reinstall it again. The process can fix any problems you’re experiencing.

    To do this, right-click the app’s icon and select More > App settings > Reset. The option is directly below the Repair option.

    Resetting an app will delete all of its local data.

  7. Reinstall the app. If you know what app is causing the conflict, uninstall it and then reinstall it again as its installation may have become corrupted or an important file may have been deleted.

  8. Disable some start-up apps. Press Ctrl+Alt+Del, then select Task Manager > Start-up. The apps on this list are the ones that automatically start up and run in the background when you turn on your computer. They can use up resources and cause conflicts. To stop the ones you don’t need running in the background from doing so, select their name, then select Disable.

  9. Run Disk Clean-up. From File Explorer, select This PC, right-click your main hard drive, select Properties, then select Disk Clean-up. This will remove unnecessary files and free up more space for apps to use.

  10. Check if the Installer Service is running. Open the Start Menu, select Run, type Services.msc, and then press Enter. Double-click the Windows Installer icon, then set the Startup type of Windows Installer to Manual. Select Start, then select OK.

  11. Reregister the Windows Installer. In Windows 7, open the Start Menu and select All Programs > Accessories > Run.

In Windows 8 and 10, open the Start Menu and simply type Run.

Type msiexec /unregister and select OK. Now, do the same again but this time type msiexec /regserver and select OK.
