Regardless how “modern” the TI-84 graphing calculator is, the software you are supposted to use to connect it to a PC (for backup and transfer of files) has not been updated for around 2 years and it plain does not work on Windows 11 on any of my machines. Yes, I have tried all their “troubleshooting”. Be aware of this, but what does still work is a third-party solution called TILP II. Using this software, in addition to Zadig to select a functioning driver, works fine for me.
