Solution 31531: TI-Nspire™ or TI-SmartView™ Software Activation Returns an Error A21 or A23.
How do I resolve errors A21 or A23 that occur during activation of a TI-Nspire or TI-SmartView Software?
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.
Errors A21 and A23 may occur during a Web Portal activation and indicate that the web portal information file is invalid or for a different computer. Web Portal information files (the webportal.acv and webportal.lic) contain information that is specific to the computer they are generated on and generated for. If you have received this error, please retry the Web Portal activation process from the beginning.
If the error persists, please gather diagnostic logs and contact TI for assistance.
