I have free basic software that was free to download from both Viking and Bernina on my computer mainly to help me transferr some of my older embroidery that is on CD to my computer than to the USB stick. My newer Viking and Bernina have basic editing software built into the sewing machines and I don't think I will need more than what I can do on the screen. I do have an older Viking software on my laptop that requires a dongle but I don't even know if it will work with the current version of windows. The current machines have all the tools I used to use on that software now in the machine.
