When you purchase a license for an Intel® Software Development Product, you are entitled to the latest version of your product, as well as any new versions which are released during your license period. When your subscription expires, you are "locked in" to the last version which released during the period, and you are limited in terms of support. A renewal license allows you to extend your support window and provides you with an upgrade path for new versions, premier technical support, and associated resources.

Renewals start from your subscription end date for the serial number that you renew. Example: If you apply a renewal serial number to an original license which had a subscription end date of 10/1/2008, then your renewal license will have a valid subscription from 10/1/2008 to 10/1/2009 no matter when you registered your renewal.

While a renewal license is more cost-effective than purchasing a new version, we do not support pro-rated renewals; renewal licenses are applied to the last day of your previous license period and “extend” the support services for the length of the renewal you purchased. In other words, if you purchase a one-year license renewal with two months remaining on your original license, you will have one year and two months of full support. If you purchase a one-year license renewal three months after your previous license expired, you will only have nine months of support remaining. Licensing costs vary by product, however generally if your license expired more than two years ago, a new license costs less than purchasing a three-year renewal.
