Sieg: I have windows 8 and had no problem. I just downloaded it and then opened it from the icon on the "start" window. I could not get it to open just from the directory. Marsh: I didn't actually upload any fabrics but I think if you scanned them and then imported them they should work similar to EQ. If the import doesn't work I would just use an approximation of the colors from the color wheel and then set a key to "translate" them. Another possibility is importing fabric samples from the manufacturer.
