Fix the iTunes Win­dows 10 Installer Pack­age Error

iTunes is a severely bloated application. It’s slow, clunky, and works woefully on Windows 10. And the fact that it relies on multiple related applications to function properly only serves to worsen the experience. Then there’s the notorious ‘Windows Installer Package’ error that can put a dent to your day.


Usually, the ‘Windows Installer Package’ error shows up whenever you attempt to update or reinstall iTunes. That has been a known issue for several years and occurs due to conflicts with the Apple Software Update utility that’s installed initially alongside iTunes.


An improperly configured instance of Apple Software Update is the most likely culprit behind the ‘Windows Installer Package’ error. Hence, the obvious way to patch things up involves repairing it. Fortunately, a brief visit to the Apps & Features panel should help you do that.

Step 1: Open the Start menu, type apps & features, and then click Open.

Step 2: On the list of apps that show up, click Apple Software Update, and then click Modify.

Step 3: On the pop-up window, click Repair, and then follow the remaining onscreen instructions to repair the Apple Software Update.

Step 4: Click Finish when prompted to complete repairing Apple Software Update.

Step 5: Download iTunes from Apple’s official website.

Step 6: Run the downloaded file, and then click Repair when prompted. That should reinstall and update iTunes to the latest version, and you likely shouldn’t encounter the ‘Windows Installer Package’ error.

If you do run into any issues again, let’s see what’s on the cards next.



For instances where repairing Apple Software Update doesn’t seem to work, you need to use the Microsoft Program Install and Uninstall Troubleshooter. This utility detects and fixes persistent problems with installed applications. In this instance, you need to configure it to remove Apple Software Update. You can then reinstall the latest version of iTunes without hassle afterward.

Step 1: Download the Microsoft Program Install and Uninstall Troubleshooter, and then run the downloaded file.

Step 2: Click Next, and then wait for a moment while the tool scans for potential issues on your PC.

Step 3: Select Uninstalling. Once again, wait for a moment while the tool scans for registry-related issues.

Step 4: Select Apple Software Update from among the list of applications, and then click Next.

Step 5: Click Yes, try uninstall when prompted.

Step 6: Click Close to exit the Microsoft Program Install and Uninstall Troubleshooter.

Attempting to reinstall the latest version of iTunes won’t pose problems from now onward. If you come across the error again, run the Microsoft Program Install and Uninstall Troubleshooter, uninstall iTunes in addition to Apple Software Update and then try again.


Rarely, the Microsoft Program Install and Uninstall Troubleshooter can fail to resolve the ‘Windows Installer Package’ error. In such instances, you need to download and install a free third-party uninstaller such as Revo UninstallerAbsolute Uninstaller, or CCleaner to to delete iTunes and all related applications.

Step 1: Download and install the free version of Revo Uninstaller.

Step 2: Right-click Apple Software Update, and then click Uninstall.

Step 3: Revo Uninstaller should automatically create a System Restore point and prompt you to remove iTunes. Click Yes to confirm.

Step 4: After removing iTunes, select the radio button next to Advanced, and then Scan to search for leftover items.

Step 5: Remove all detected registry entries, and then click Next.

Step 6: Remove all leftover folders related to iTunes, and then click Finish.

Step 7: Repeat the procedure for other iTunes-related software on your system in the following order:

  • Apple Software Update
  • Apple Mobile Device Support
  • Bonjour
  • Apple Application Support 32-bit
  • Apple Application Support 64-bit

After that, restart your PC, and then install the latest version of iTunes. There’s little chance that you’ll encounter the ‘Windows Installer Package’ error again.



Hopefully, the solutions above worked, and you’ve either reinstalled or updated iTunes successfully. However, you can also consider switching to the Windows Store version of iTunes and completely forgo similar headaches in the future.

In a nutshell, it carries less bloat than its desktop counterpart, feels slightly less sluggish in terms of performance, and updates automatically alongside other Windows Store apps. Sounds good, right?
