You can extend your commercial, academic, or enabling license by ordering support renewals for your product from the reseller. After receiving your renewal serial number, you will need to register it at the Intel® Registration Center. You will then need to follow the directions shown to install your new license file.
To extend your non-commercial license, go to the non-commercial software website and register again for your non-commercial product.
Evaluation licenses are limited to thirty days from the time of registration.
