Fix: QuickTime no Longer Works after Windows 10/11 Upgrade

When switching to a new operating system, there’s always a concern about whether your favorite apps will work on your new operating system.

According to reports, QuickTime no longer works after the upgrade from Windows 7 to Windows 10, so let’s see if there is a way to fix this issue.

What to do if QuickTime doesn’t work in Windows 10?

Users report that they can’t install QuickTime on Windows 10 to open QTL files, but there are a few workarounds that will allow you to install QuickTime even if you’re using Windows 10.

Before we start, you’ll need to download QuickTime for Windows as well as WinRAR or 7Zip. Remember the location where you’ve saved the QuickTime installation because you’ll need to visit that folder a couple of times to complete this process.

For simplicity, it’s best to save the installation in the C:\QT folder.

Repair the QuickTime installation

1. Right-click the QuickTime installation and select the Extract Here option.
2. Download the TRANSFORM file.
3. Extract the content from FIX.zip to the C:\QT folder.
4. Run and install AppleSoftwareUpdate.msi and AppleApplicationSupport.msi.
5. Right-click QuickTime.msi file and choose Troubleshoot compatibility.
6. Wait for the wizard to complete the scan.
7. You should get a notification saying that Skip Version Check workaround has been applied.
8. Now click Test the program and run the installation.
