Dear Sir.
I have Visual Prolog 10 Build 1002 Commercial Edition.
How can I update it to Visual Prolog 11 version?
Thank you very much.

Hi, Faddey.

You can upgrade your license using the order form. You must login with your email and password, and then you will need to fill in the license key of the license you want to upgrade.
