Please be advised this license type will be discontinued on November 7, 2023, and your current software will no longer be updated. Converting to a new, account-based license before that date is recommended. In most cases you can receive an equivalent subscription length free of charge by contacting TI-Cares.
For now, you may still activate and use your current software for the full license term, but you will not be able to reactivate or download this software again after November 7. If a new activation or download is needed after that date, you must contact TI-Cares to acquire a new account-based subscription.
If when you activate the software you receive any of the following errors:
- The TI server is currently unavailable [Error A11]. Please try again later.
- The TI server is currently unavailable [Error P26]. Please try again later.
- The TI server is currently unavailable [Error P27]. Please try again later.
- The TI server is currently unavailable [Error P99]. Please try again later.
