Installation Instructions

No additional installation required.

Original CX and older

N-Link requires some generic USB drivers, rather than the ones that TI provides. To install them, download Zadig and open it. First, select "Options" at the top and check "List All Devices":

Next, select "TI-Nspire(tm) Handheld" in the dropdown menu, and click "Replace Driver":

Now, you're all set. Unplug and plug the calculator back in to use it, and then launch N-Link.

If you get a "Windows protected your PC" SmartScreen notice when attempting to install N-Link, select "More info", and then click "Run anyway".

If you'd like to use the official TI-Nspire software again, you'll need to uninstall the WinUSB driver. To do so, right-click on the start menu and select "Device Manager". Expand "Universal Serial Bus Devices", right-click on "TI-Nspire(tm) Handheld", and click "Uninstall device":

Now, check "Delete the driver software for this device":

After unplugging the calculator and plugging it back in, you're all set to go.

macOS

If you get some permission denied errors, follow this guide by Apple: https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac

Linux

This isn't needed on platforms such as Chrome OS or Android

You'll first need to install some udev rules to ensure there are no permission errors, even if you're using the web version. Create the file /etc/udev/rules.d/69-n-link.rules with the following contents: 
# TI-Nspire
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="e012", ENV{ID_PDA}="1"
# TI-Nspire CX II
SUBSYSTEM=="usb", ATTR{idVendor}=="0451", ATTR{idProduct}=="e022", ENV{ID_PDA}="1"
 Finally, run udevadm control --reload-rules && udevadm trigger.

Deb

Run sudo dpkg -i n-link_version_amd64.deb

AppImage

Run chmod +x n-link_version_amd64.AppImage && ./n-link_version_amd64.AppImage. After that, you'll likely be able to simply double-click the file from then on.
