I was lucky that I had an older Windows XP laptop that I could use for my embroidery machine software. My software is Magic Box and the manufacturer said it won't work with Windows 7 (my new computer) because Windows 7 is 32 bit and the old software I have is 16 bit. Now I have no idea what all that means! I just think the software should have an update available, we paid lots of hard earned money for it.
