there is quite a good software for vinyl cutting which has a pop up drivers box , which has pcut drivers in it. software is 30 days free trial then fairly low cost. Its called "SIGNGO"
just a comment about the creation pcut 630, The usb cable, some low quality cables won't work at all, with this cutter. fine for printer but not this cutter, higher quality seems to work good, stange but true.lol
