some of the old embroidery programs for the Huskqvarna do not work on the new windows formats. My 1+ has to have a windows 96 or older. It does not matter if you have the right port or not if the program will not run on the new computer. To make my reader writer to work on a new computer I would have to buy a whole new embroidery program and then Huskqvarna will not guarantee that that would even work.
