Running latest Windows 10 under Parallels Desktop on Mac Pro OS Sierra 10.13.4. PixelCNC fails to load with a "cannot find multicore processor" error. Just dropping a note to let you know and not seeking a fix.
Program is running fine on my Lenovo Helix with same version of Win 10.
CNC is an Inventables 1000 x 1000. I'll post after I make a few trial carves.
