Hi @Cabinfourus. The error message is correct and expected. The ZIP file does not have the required format for installation via the Arduino IDE's Sketch > Include Library > Add .ZIP Library... feature.

You can install it by following the instructions from the Grbl wiki:

https://github.com/gnea/grbl/wiki/Compiling-Grbl#if-you-are-using-arduino-ide-2x

If you have any questions or problems while following those instructions, please post about it on the Arduino Forum:

I'm certain we will be able to help you out over there.
