Solution 31372: TI-Nspire™ Family or TI-SmartView™ Family Software Activation Returns an Error C01 or C04.

How do I resolve errors C01 or C04 that occur during activation of a TI-Nspire or TI-SmartView family 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 C01 and C04 can occur when the user account does not have sufficient permissions. Activation requires an account with Local Administrator permissions. To resolve these errors, you will need to activate the software from an account with Local Administrator access.

  • For personal computers, please contact your computer's manufacturer for support on changing user permission levels.
  • For computers managed by an IT department, please contact your Administrator to receive the appropriate permissions.

If you have obtained Local Administrator permissions and error persists, please gather diagnostic logs and contact TI for assistance.
