Double-click the iTunes icon on your Windows PC and, instead of your music library, you get a cryptic message about webkit.dll? Let’s clear something up first: this error is strictly a Windows problem. It means one or more of Apple’s software components — or the registry entries they left behind — are broken. The good news is that a thorough cleanup fixes it every time. Here’s how.
Why you see the webkit.dll error
iTunes for Windows doesn’t run alone — it relies on a bundle of Apple components (Apple Software Update, Apple Mobile Device Support, Bonjour, Apple Application Support, device drivers, and iTunes Helper). When one of them is corrupted or only half-removed by a previous uninstall, iTunes can’t load its rendering engine and crashes at launch with the webkit.dll error. That’s also why simply reinstalling iTunes over the top rarely helps: the damaged parts survive. You need to remove everything and start fresh.
Step-by-step: the full cleanup fix
Work through the whole checklist — skipping steps is how the error comes back.
Step 1 — Uninstall every Apple component, in this order
Open Settings > Apps (or Control Panel > Programs and Features). You need administrator rights for this. Remove each of the following, one by one, in this order:
- iTunes
- Apple Software Update
- Apple Mobile Device Support
- Bonjour
- Apple Application Support
- Apple device drivers
- iTunes Helper
When you’re done, search the program list for anything else from Apple and confirm every component is gone. Leftover pieces are exactly why the error returns after a “simple” reinstall — don’t leave any behind.
Apple maintains its own guide to removing and reinstalling iTunes and related software components for Windows, which walks through the same removal order.
Step 2 — Clean the registry and restart
Run a registry-cleaning utility to sweep up the orphaned entries that Apple’s software left behind (CCleaner is a popular choice for this). Let it scan, clean, then restart your computer — the reboot matters, since it clears any locked files still in use.
Step 3 — Download iTunes fresh from Apple only
Head to apple.com and download the latest iTunes installer — only from Apple’s official site. Third-party mirrors are a common source of corrupted installers, which can drop you right back where you started. Install it fresh with the default settings.
Launch iTunes. The webkit.dll error should be gone, and your library should open normally. If you previously had connection trouble between your devices, our guide to measuring iPhone-to-Mac transfer speed over cable can help you check that your phone and computer are talking to each other properly.
If it still doesn’t work
If the error persists after a full cleanup, make sure Windows itself is up to date and that no third-party antivirus is quarantining Apple components — security software sometimes blocks Bonjour or Apple Application Support silently. You can also try installing iTunes from the Microsoft Store version instead, which keeps its dependencies separate. And if you sync content between devices, our message sync setup guide shows how to get your iPhone and Mac talking once iTunes is healthy again. As 9to5Mac has noted in coverage of Apple’s Windows software, a corrupted component stack is almost always the culprit behind iTunes refusing to start.
Frequently asked questions
Can this error happen on a Mac?
No. The webkit.dll error is Windows-only — .dll files don’t exist on macOS. If iTunes (or the Music app) won’t open on a Mac, that’s a different problem with different fixes.
Will uninstalling iTunes delete my music library?
Usually not — your media files and library database live in your Music folder and survive the uninstall. Still, back up your iTunes library folder before you start, just in case.
Conclusion
A webkit.dll error looks scary, but it’s just Apple’s Windows components tripping over themselves. Remove every one of them, clean the registry, restart, and reinstall from Apple — and iTunes will launch like nothing ever happened.
