  • TI_NetworkFailure

Error message: Internet connection not detected.

Resolution: How do I resolve errors ET101, ET102, ET103, ET104, ET106?

This error code usually indicates a problem connecting with the license server. If you encounter one of these errors, try the following:

  1. Make sure that your computer is connected to the internet. Verify that you can connect to https://education.ti.com/login.
  2. Verify the date and time is set correctly.
  3. Sometimes, security software, such as antivirus, anti-malware or firewall software, can block a program’s access to the internet. Make sure that security and firewall software are set to allow communication from your TI software to the internet. If this is a personal computer, please see your antivirus or firewall documentation for more information on how to change these settings. An exception should be added for https://edtech.ti.com and https://activation.ti.com to your security software. If your system only accepts a domain please add ti.com. If this is a computer that is managed by an IT department, please contact your administrator for assistance making these changes.
  4. If a service or system within your network decrypts https traffic you will need to disable this decryption for the web address https://edtech.ti.com and https://activation.ti.com. If your system only accepts a domain please disable decryption for ti.com. Please contact your service or systems support for information on how to add this exception.
  5. Other programs can sometimes also hinder a program’s ability to communicate over the internet. Try closing all other applications on your computer, and try again.
  6. Reboot your computer and attempt your activation again.
  7. Uninstall and reinstall the software.
