Add a new domain : Your domain is not licensed to utilize our installer API.

Hello,

I actually need is to add a new domain - not for the support, but to be able to install the extension in another (temporary project).

I download the full installation package but while installing it I obtain this message : "Your domain is not licensed to utilize our installer API. Please enter your domain name in your license area. If this is a local installation, please download the full installation package from your dashboard area."

Any, help? the first time i could do it easily !
