Hi,

You might have a subscription for Odoo Enterprise Online (SaaS), which doesn't allow you to download the Odoo Enterprise source code for local installations (Windows, Linux, etc.). The SaaS plan typically only gives you access to the cloud version or there might be specific restrictions in your contract that prevent you from downloading the Enterprise version for a local setup. Some contracts only allow certain deployment types (like cloud hosting).

Please review the details of your Odoo subscription. Ensure that you have a subscription for Odoo Enterprise (self-hosted/on-premise), which allows downloading the software for local installations. If it is correct one then contact Odoo support for assistance through https://www.odoo.com/help.

Hope this helps you

Thanks.
