If all went well, then congratulations! You have updated your operating system. If not, read our troubleshooting section below.


  • Nothing happens when I drag the file into TI Connect CE: You can manually send the file by clicking on the “Actions” button in the top bar, clicking “Send OS/Bundle to Calculators”, and navigating to the OS file you downloaded.
  • It says the operating system is not compatible: Are you sure you have a TI-84 Plus CE? The operating system given above will only work with this calculator, and you will have to download a different file for the TI-84 Plus and TI-84 Plus C Silver Edition.
  • My calculator is not connecting to my computer: There are a few things you can try. First, try pushing the cable in harder, you may have to push harder than you think you have to. Second, try using a different computer or reinstalling TI Connect CE.
