Steps to Resolve the ‘License Key Already in Use’ Error

1. Deactivate the License on Unused Devices

If the license key is activated on more devices than allowed, deactivating it on unused devices is the simplest solution.

How to Deactivate a License:

1. Log in to the software’s official Account Portal (e.g., Malwarebytes, Microsoft, etc.).
2. Navigate to the My Subscriptions or License Management section.
3. Identify the devices currently using the license.
4. Deactivate or remove the license from inactive devices.

2. Restart the Device and Retry Activation

Sometimes, temporary glitches may prevent the license key from being recognized.

Steps:

1. Restart the device on which you’re trying to activate the license.
2. Re-enter the license key during the activation process.
3. Ensure no other devices are using the same key simultaneously.

3. Verify License Usage Terms

Check the terms and conditions associated with your license key:

• Single-Device License: The key is intended for one device only.
• Multi-Device License: The key may support multiple devices but has a limit.

If your activation attempt exceeds the permissible limit, consider purchasing an additional license or upgrading your subscription.

Many software providers allow users to manage licenses online, offering the ability to revoke old activations.

Steps to Revoke Old Activations:

1. Access the software’s account management page.
2. Locate the devices associated with your license key.
