i have a old Janome 5700 and i use customizer 2000 with it and it works great with windows 7. Tell her not to throw it out. This is what i had to do to use mine.
I had to buy a new cord adapter that converted my serial cord to a usb and that way i could plug into the computer and get my designs. They sell them at any computer shop. After i bought the new cord adapter you have to slow down the port speed because its too high for the old program. I too called Janome head office and they had no good infromation for me but to say well it's old and there is nothing we can do. Well i found a way and then called them back to say , yes there is and told them what i did and the lady on the phone was shocked...hehehe she said she would pass on the information to others.
SO you have to find someone who knows about computers and how to get into where you set the usb speeds up and slow it down.
hope this helps

I would go to the Janome web site and see if you can find updates or someone to ask.
