Texas Instruments software, sold as a School-Managed Perpetual License, requires a free, annual reactivation. In order to renew your license, you will need to log into your Texas Instruments Education Technology Software Service Center Account. This is the account you used when you first claimed the software. Once logged in, you can find step by step instructions on renewing an SML at the following link:

For more information regarding software reactivation, you will need to contact Texas Instruments directly.
Note: Texas Instruments no longer sells perpetual license software. Because of this, your perpetual-license software will no longer be updated. If you need the functionality of the newer TI emulator software, you will need to contact TI to have your licenses converted to a multi-year subscription license.
