I don't know which Singer she has, but mine only works in "compatibility mode" with Windows 7. My software will not run on a Windows 10 machine. My software was written for Windows XP. Unfortunately, the embroidery part of the machine will not work without the software. The Singer website might be helpful for her. I hope her software is more recent than mine.
Thank you for the help, my daughter remembered that she had an out of date laptop with XP so will try to use it with her machine!! Again Thanks dear!
I hope it helps! The laptop is a great solution. It doesn't need to go online to make it work.
