License Activation Fails with 'Key Already Used' Error

Below are a few steps you can follow to troubleshoot and potentially resolve this issue:

1. Confirm License Usage

• Verify that the license key you’re using isn’t already activated on another instance.
• If you attempted to reuse the same license key on a reinstalled or cloned instance, the system may detect it as already in use.

2. Check for Residual Activation Data

• Some products store activation details locally. If you reinstalled or migrated your environment, ensure that old activation data is completely removed.
• Look for any configuration or hidden files that might cache activation details and remove them as instructed by the product documentation.

3. Use the Correct License Key

• Ensure the key you’re applying is intended for the current instance or environment.
• Double-check that there were no mistakes or copy-paste errors during activation.

4. Contact Support

• If you’re confident that the key should work for your instance, it may be necessary to contact the vendor’s support.
• Provide them with details (such as the error message and instance identifier, if available) so they can check the activation history and help release or reissue a key if needed.

Following these steps should help you identify whether the issue is due to residual activation data, a conflict with an existing installation, or if you need a new key from support. Let me know if you need more detailed guidance on any of the steps.
