I need to dowload a KMS License key

Dear @Oscar Lopez,

Thank you for posting your question on the Microsoft Q&A forum.

If you are not seeing a KMS key option in your Volume Licensing account, please first ensure that you are assigned the appropriate Administrator role or have sufficient permissions in the Volume Licensing Service Center (VLSC) or Microsoft 365 Admin Center to view product keys.

If the issue persists, we recommend creating a support ticket through the following link: Contact volume licensing support
The Microsoft Volume Licensing Support team specializes in licensing-related matters and has the necessary access and escalation channels to review and handle this type of request accurately and effectively. Thanks for your patience and understanding so far. 

I hope this information helps. If you have any additional questions, please feel free to let me know.

To obtain a KMS license key, you typically need to access your Volume Licensing account. If you do not see the option for the KMS key in your account, you may need to ensure that you have the appropriate permissions or roles assigned, such as the VL Administrator role.

If you still cannot find the KMS key, you can contact the Microsoft Activation Center for assistance or check the Product Keys section of the Volume Licensing Service Center. You may also need to provide details about your agreement or enrollment number to add the KMS key to your contract.

For further information, you can refer to the documentation regarding volume licensing and KMS activation planning.
