I'm afraid that Carbide Motion isn't supported on Windows XP --- the install can be run there, and that's how one gets the driver installed, but the program itself probably won't run (it used to run on Vista FWIW)..
You can run the program to install the driver, and then use one of the opensource communication / control programs: https://www.shapeoko.com/wiki/index.php/Communication_/_Control or a commercial option: https://www.shapeoko.com/wiki/index.php/Commercial_Software --- current favourites are:
- Universal G-code Sender --- for folks who use Java
- bCNC --- old-school option for folks who like Python
- ChiliPeppr --- for folks who don't mind their software in the cloud
- EstlCAM --- for folks who want commercial software w/ CAM baked in
That said, my suggestion would be to just buy an inexpensive Windows tablet and use that.
