What Is Driver Booster 13 and Why the License Key Error Appears
Driver Booster 13 by IObit is one of the most widely used driver updating tools for Windows. It automatically scans your PC for outdated, missing or faulty drivers and updates them with one click. The Pro version unlocks faster download speeds, automatic backups, and more stable driver sources — but you need a valid license key to use these premium features.
Sometimes, when you enter your purchased key, the program displays an error saying “License Key Already in Use” or “Activation Failed.” This usually means the license has been activated on more computers than allowed, or the activation data on your system doesn’t match what IObit’s servers expect. In rare cases, a network glitch or system change (like reinstalling Windows) can also trigger the message.
Common Causes of the “License Key Already in Use” Error
To solve the problem effectively, it helps to understand the most common triggers:
- Exceeded Activation Limit: Most Driver Booster Pro keys are sold for a specific number of PCs. If you’ve installed it on multiple computers, the key may reach its limit.
- Recent PC Changes: Reinstalling Windows, changing your motherboard, or upgrading your hard drive can make IObit’s system think it’s a new computer.
- Expired or Shared Key: Using a key from an unofficial source can result in conflicts or revocation by IObit.
- Network or Firewall Issues: Sometimes, your PC can’t connect properly to the activation server.
- Old Program Files: Leftover files from a previous installation may interfere with the new activation.
Step-by-Step Solutions to Fix the Error
Follow these methods one by one until your issue is resolved.
1. Double-Check the License Key
Make sure you’ve typed the key exactly as it appears in your purchase email. Watch out for confusing characters such as “O” vs. “0” or “l” vs. “1”. If you copied and pasted, ensure there are no extra spaces at the start or end.
2. Confirm How Many PCs the License Covers
Check your purchase confirmation or IObit account to see how many devices your license supports. If you’re over the limit, deactivate one of the other installations first (see next step).
3. Deactivate Driver Booster on Other Devices
Open Driver Booster on the other computer where it’s installed, go to Menu > My License > Deactivate. This frees up the activation slot so you can use it on your current PC.
4. Sign In to Your IObit Account
If you bought the key directly from IObit, sign in at https://www.iobit.com/en/mylicense.php. Here you can manage your licenses, see which PCs are linked to each key, and release old activations.
5. Reinstall Driver Booster 13 Cleanly
Corrupted or leftover files may interfere with activation. Uninstall Driver Booster completely using the official uninstaller or a trusted removal tool. Restart your PC and download the latest version from the official IObit website. Install it fresh and then re-enter your key.
6. Disable VPN, Proxy or Firewall Temporarily
A VPN, proxy or strict firewall can block the activation server. Temporarily disable them, activate Driver Booster, and then re-enable your security settings.
7. Contact IObit Support
If none of the above works and you’re sure your license is legitimate, contact IObit Support. Provide your order ID, license key, and a description of the error. They can manually reset your license or issue a new one.
Preventing the Error in the Future
Once you’ve fixed the problem, follow these tips to avoid it reoccurring:
- Keep Track of Your Activations: Note which PCs you’ve installed Driver Booster Pro on.
- Use Only Official Keys: Avoid “free” keys from unofficial websites — they’re often shared, blacklisted or unsafe.
- Deactivate Before Uninstalling: If you’re moving to a new PC, deactivate your license first.
- Create a Backup of Your Key: Store your key in a safe location so you can re-enter it after reinstalling Windows.
- Stay Updated: Always download the newest version from the official IObit site to avoid compatibility issues.
Why This Matters
Driver Booster Pro is popular because it saves time and ensures your PC runs smoothly with up-to-date drivers. But if you can’t activate it properly, you lose access to the very features that make it valuable. By understanding the “License Key Already in Use” error and following the steps above, you can get back to updating drivers without interruption.
