Cause of Windows Installer Package Errors

When you get an alert or warning message telling you there's a problem with the Windows Installer package, it 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 the running apps, or a graphics driver error.

Windows Installer package errors can also be caused by seemingly random system glitches with no major problem behind them at all.

How to Fix a Problem With Windows Installer Package

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

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

  2. Update Windows. Performing a Windows update scans the device during the update process and fixes several conflicts that may be present. The update process also updates the operating system and drivers, which could repair the cause of the Windows Installer package error.

  3. Update Windows apps. If you haven't updated the apps on your computer, now is the time. Besides adding new features, app updates can also improve security and remove 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 scan and provide solutions for any app problems that cause this error message to occur.

  5. Repair the app. On Windows 10 and Windows 8, right-click an app's icon or tile, and select More > App settings > Repair. This scans only the app and fixes any errors in its coding.

    On Windows 7, select 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 deleting it completely and reinstalling it again. The process can fix any problems you experience.

    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 deletes all its local data.

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

  8. Disable some start-up apps. Plenty of Windows apps automatically run on start-up. For some things, this is convenient. For most, it slows down a computer. Disable the ones you don't want.

  9. Run Disk Clean-up. A simple disk cleanup is good PC maintenance, and it also frees up space and helps Windows run more smoothly. It can also help programs, like installers, run more efficiently.

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

  11. Reregister the Windows Installer. In Windows 10 and Windows 8, open the Start Menu, and type Run. In Windows 7, open the Start Menu, and select All Programs > Accessories > Run. In the Run dialog box, enter msiexec /unregister and select OK. Then, do the same again but this time enter msiexec /regserver and select OK.
