xtool D1 manual asks to download this file before configuring the LB software. Cannot run that file with LB. I receive a message “to find a version for your laptop, check with software publisher.” Laptop has version 1.3.01 loaded. I believe it as a GRBL controller.
This is not a file that you run. I’d advise you to follow the instructions closely on that.
You need to use the Import button in Devices window to load the file.
